Gourmet Burger Kitchen in Newham

I had really bad experience in the restaurant. We Order burgers along with the fries. The fries contain a long hair and they give us the fries when we asked them, their service is too slow. People come after us they all got the drinks we waited 30 min for the drinks and when they serve the drinks they make it messy and the bartender she is very rude while serving.

Came with my sons, really nice food and excellent service

I had a great experience at GBK amazing service and food I would like to mention the chef names Fofana and Iwona They made an amazing meal great taste and quality of food Which I happens to ask the person in charge Viraj who was the great at help to choose the best burger meal to have.

It was an amazing lunch time here the food was amazing and the drinks too. I would like to appreciate the chef Fofana and Iwona who made an amazing burger meal. I happens to ask the chef names to Aastha who was In-charge there, great hospitality service by her as well guided us to choose the right meal according to our requirements.

Best food and nice service. Value for money. Good service from Viraj and Alisha.

Lots of deals, so hamburgers are pretty cheap with Really good ones and good variations! The food comes quick to your table. The service is excellent most of the times, with lots of smiley faces. I've been there 4 or 5 time and I really like it. Is not over priced (many chains are) and you get free unlimited peanuts! Update 2024: Came here last night, today all day with stomach aches since the morning. Rations are also smaller. But I saw something not great: in the kitchen I saw someone spraying anti-bacterial cleaning product extremely close to the food toppings. Is impossible that no chemical went into the food. Is this why I had horrible stomach problems for two consecutive days right after eating here?

I was there with my friend for a dinner , and we ordered two burgers and a vanilla shake , it's takes almost half an hour to get our food and the food was not tasty , the only thing I like there is the vanilla shake

I visited this Gourmet Burger Kitchen last week, and it was a great experience! The burger was packed with flavour, and the ingredients tasted really fresh. The fries were perfectly crispy, and the milkshake was a nice touch. The staff was welcoming and quick with service. It's definitely worth a visit if you love a good burger!

I recently visited Gourmet Burger Kitchen and had a fantastic experience. The burgers were delicious, juicy, and cooked to perfection. The menu has a great variety of options, including veg/vegan choices, and the sides were just as tasty. The service was quick and friendly, and the atmosphere was relaxed. Overall, it's a great spot for a satisfying burger! Would definitely recommend it.

Small portions, qué when the restaurant was almost empty, dull ambience.

Great food. Service also friendly. Not many places still cooks on flamed grills, but GBK does, and beef taste nice and smoky. It’s a shame they closed Greenwich and O2 branches, as they were our local ones :(

The chef Rajeev’spresentation was stunning, and the flavors are even better! A true culinary artist.Likes the flavours of the chicken.Nice service and nice atmosphere.. See you again guys..

I ordered at 8:33 however I waited yet I still have not received it.

Food was terrible, a cold soggy pile of bread and meat. Ordered a smash burger, receieved a regular burger. Didnt reveive my drink, wasnt checked back on so i left and bought my dinner at 5 guys instead. I also witnessed a short white man in a suit, who i assume is the manager, berating and swearing at his staff on the dining floor which was really unpleasant and uncomfortable to experience whilst dining out. The shop floor staff looked miserable and exhausted also.

Fantastic burgers. I was enjoying the food. I still remember that taste of the best burgers in the town. Been there twice and looking forward to try sth again.

We made a huge order of 6 burgers, 5 chunky fries, 5 drinks and 2 onion rings. 2 burgers, all 5 fries and both onion rings were missing. Shocking. I even commented on the fact that only 2 bags wee given to me, but the receipt showed the entire order and I trusted that everything was there. You can imagine how we were happily anticipating this order. We are all now snacking on crisps to fill the gap and I’ve made a second McDonald’s order for 2 meals for the children which we are now waiting on.

Asked for Burger with no mayo and got burger with mayo. Chips still hard and wait time of 20 mins. When only 3 groups in restaurant. They did offer to re do my burger and told me it would only take 5 mins this time not 20 so not sure why we had to wait so long the first time. When I refused I was given 2 x £10 voucher but as I won't come back they don't really help.

Was served by a gentleman called viraj. Excellent service from him. Was very patient and explained everything super clearly. Definitely needs a pay rise!

GBK used to be a good place to grab a proper burger - gone are those days. They have now joined some other burger places in a massive shrinkflation move - increased prices, burger patties ever thinner, milkshakes in the same cups as before but obviously reduced portions. Not sure I'm planning to go back any time soon on this basis.

I ordered a classic burger medium cokeed, and I could only taste the burned on my bread, bacon, and beef patty. I just wasted £12.50.

My visit to GBK on Saturday was terrible. The restaurant was packed so understandably, the food took longer than expected. We received our food 50 minutes after we ordered. Halfway during our wait, we ordered an additional side. When our first order arrived, it was cold and half the size the burgers at other GBK branches I’ve visited were. We had to wait another 45 minutes for our other order before I went to complain. I waited in the queue behind 3 other people who were complaining about waiting for their food for between 50 mins to 1.5hrs! We decided to leave at that point. In the future, the manager should at least warn customers of the expected wait time rather than just sitting customers down. However, we did have a lovely staff member who apologised for our wait.

I visited this place yesterday and must say that atmosphere was horrible, never experiened this in my life before! Manager screaming in front of us at his employees when restaurant is obviously short staffed. Just a quick reminder: should be grateful that you have at least someone working for you!

On the second floor of the Westfield-Stratford ahopping center. You have several different burgers you can choose, including a couple of vegan and vegeterian options! Then you can customize your burger, including how many patties you want, how you like your patty cooked (medium to well-done) and other extra contents. As for the burgers, they were ok... just ok. Not the worst I have had, but defintinitly not the best!

These people are a bit lost with the new menu! I don’t think they can tell the difference between a classic burger and a Smashburger! Go all the way down stairs, to the first floor McDonald’s at guarantee you can have a better meal!

I waited over 30 minutes for a simple hamburger and chips. Paid 20£. The service was incredibly slow. Very disappointing. Won’t be returning.

Very overpriced - I paid £11.50 for this sad-looking burger (Korean BBQ chicken). It tasted quite nice but disappointed with the lack of fillings. And you had to pay for fries separately - when you get such a poorly filled burger and pay that price, you’d expect chips in the price. Won’t be returning as there’s plenty other better burger places around. No atmosphere either, very quiet. Doesn’t meet the title of ‘Gourmet’ at all!

Drinks took forever to arrive, they need more staff on the floor. One to serve drinks, one to wait around the tables and one to escort to tables, and two to serve food. the burgers were being made quite quickly so people in the kitchen were clearly working fast but the shop floor people were extremly slow. customers next to us were also complaining about drinks and left unhappy. poor service overall. wouldnt come back

First time at GBK Meal was top quality Staff could not have been more helpful

Very nice milkshake and burger. Great service too

Overpriced £11.50 for a small chicken burger. Chicken was hard and lack of flavour.. It's was so plain!! Portion of truffle chips barely has any truffle sauce for £6! First and last time in this place...service was disaster, staff has not clue of what they are doing...I felt robbed by the price and the quality of food..

Hadn’t been to GBK in some years. I remember it being alright, though. Recently came here on a date night and it exceeded expectations. I doubled up on the Taxi Driver which was delicious and my partner was very satisfied with the cheeseburger also. Fries were simple and importantly, well-seasoned. Good, simple food done right at fair prices. Service was smooth and smiley. Ambience was pleasant too. Would return.

We received our food quickly, but the drinks were missing and took at least another 10 minutes to arrive and my father had to go get them. The staff wasn't helpful at all. Additionally, my sweet potato fries took so long to arrive that I had already eaten half of my burger by the time they did.

I came here with a large group of friends. The service was very helpful, polite and efficient.

I visited Stratford GBK, couple of days before with my group. The staff asked us about allergens and suggested us few burger options. They have good halal options with vegan burgers as well. The atmosphere is also good with very fast service. Nice options of bottomless drinks Strawberry elderflower is one of my favourite. I would like to recommend this place.

Yesterday we visited your establishment, we ordered 5 burgers and one of them was with old spoiled meat, which smelled terribly. The manager assured us that the meat smelled like onions and was not spoiled, although it was clear that this was not true. We didn't eat that burger, but the other burgers that didn't stink did, and it was a big mistake because one member of our group has been in bed all day today with stomach cramps and food poisoning

Food was pretty good and came out quickly. Washrooms needed to be cleaned and there was no soap on ladies or men's.

Today, I visited [GBK] and placed an order for two classic chicken burgers with some fried chips and onion rings, which are well-known at their establishment. However, I encountered an error in my order as I received sweet potato chips instead of the regular chips that I had requested. The quality of the burger was satisfactory, but it did not offer any exceptional value compared to its price point.

I went here for a dinner and the service was quick and the staff friendly. Good Vegan options on the menu.

Great burgers from here, was glad to see that they ask you how well done you want your burger and they actually made it well done, a kind member of staff also sorted out a refund when I accidentally ordered an extra burger, so thank you!

The food is great. My favourite burger place in London to be honest. I love how they cook it medium-rare. Also the selection of side dishes is amazing. That being said, the waiting time is usually long.

I ordered potatoes, but it took a long, very long time

Delivery was smooth and person very pleasant

The food was really good and the deals that were on were fantastic. Kids eat for £2 with a full paying adult and they had sides for 3 for £10. The customer service was disappointing. Some of the staff just didn't seem too bothered and not even said anything when we asked for refills. I ended up going up to them as they weren't taking any notice of us even though we were waving to them from our table. I could understand if it was really busy but it wasn't too bad when we were there. It's our local GBK so we will probably be back but I hope that the customer service in this restaurant improves!

Classic vegan burger was sloppily arranged and flavourless and the fries were coldish . For the price I did not think it was worth it

Our server was Ollie. He was really helpful, attentive, relaxed and professional. We had a great experience and will definitely be back!

My food was 30, mins late! Food tasted great but was quite cold

I'm giving 3 stars because the person I suppose was the manager and the girl at the till were nice, but everything else was quite disappointing. The portion of the chips for the meal deal was terrible, I could count them on my hands ✋🏼. Things have changed, the burger wasn't that tasty, at least not as I remember. Gbk used to be amazing, but I guess those times have come to an end. You don't get what you pay for in any way. Please tell the host to smile and communicate with people, as a host he's supposed to welcome you and make you feel comfortable, but he seemed lazy, bored and pissed altogether. He didn't even explain me how to order. Bless the girl at the till that was trying to do by herself a job that was meant to be for 3 people minimum. You should be embarrassed to bring to the table such ridiculous portions.

Food was terrible and the service is almost nonexistent as you have to ask for everything including simple things like a napkin and cutlery. Burger was under seasoned, burnt and swimming in oil till the point the bun fell apart as soon as i picked it up. Anaemic chicken wings. Dirty water glasses. Sticky tables.

I recently visited GBK stratford with my family, it was a horrible experience. I’m a regular GBK customer for a long time in the stratford, O2 and St.pauls branch and it was a shame to know that this branch is making their milkshakes in a different way and it tastes really different from the milkshakes I had from their other branches recently. Also cola drinks were very less in quantity for 3.40 quids which is from the tap and it tasted flat. The food was okay but the waiting time was so long for drinks and food that we haven't received our food even after we where done with our drinks. The guy was just taking people inside without even clearing the tables. It is very dissapointing that GBK is providing this kind of service. The restaurant seemed to be severely understaffed and constant changes in the management is leading to inconsistencies in the quality of standards and services. I hope the GBK management would take some actions for these situations. I would never be coming again to this branch.

Worst service ever, do not visit this place. I had the worst experience over here . The food took too long to arrive and the drinks took even longer , it only came after I had finished my food and was about to leave none of the staffs came to check on the food or drinks and they were taking in people to uncleared tables and cleaned them while we were sitting there. Even though it wasn’t that busy. The fries were cold and when asked about it they didn't give me any reply. Overall a disaster of an experience.

Food was very tasty and reasonable price. My baby spilt the milkshake and Libin didn’t hesitate to give us another milkshake , very good customer service will definitely return.

Disappointing Experience at GBK Restaurant I recently dined at GBK Restaurant and unfortunately, it was a highly disappointing experience. From start to finish, there were several issues that severely impacted my enjoyment of the meal. Firstly, the service was incredibly slow. It took an unacceptably long time for our orders to be taken and even longer for our food to arrive. Additionally, getting drinks was a nightmare as it seemed the staff were more focused on other tasks rather than attending to customers' needs promptly. Furthermore, the customer service was lacking. Not once did any staff member inquire about our dining experience or if we needed anything. It felt as though we were invisible to them. The cleanliness of the restaurant was also subpar. Tables were left dirty, and it was evident that they hadn't been properly cleaned between customers. This lack of attention to cleanliness is unacceptable, especially considering the current hygiene concerns. To make matters worse, there was no one available to address our concerns or doubts. It seemed like everyone was in a rush, with no staff members willing to take the time to assist customers or address any issues they may have had. Overall, my experience at GBK Restaurant was extremely disappointing. The slow service, poor customer service, lack of cleanliness, and absence of staff availability made for a frustrating dining experience. I would not recommend this restaurant to others and am unlikely to return in the future.

I recently dined at Gourmet Burger Kitchen for lunch, opting for the chicken burger accompanied by onion rings. While the food was satisfactory, it lacked the wow factor considering the price point. The timing of service was disappointing; my drink didn’t arrive until after I had finished my meal, despite being the only patron initially and later joined by only two other tables. This delay was particularly inconvenient given my limited lunch hour, which should have allowed for a quick turnaround. Regrettably, I left the restaurant feeling unsatisfied and, frankly, still hungry.

As a long-time customer of GBK in Stratford, I recently had an extremely disappointing experience with their service. Upon entering the restaurant, I noticed that all the tap water glasses were dirty and hadn't been cleaned properly. Furthermore, the tables were cluttered with empty plates, and it took an excessive amount of time for the staff to clean them after customers left. It was evident that the restaurant was understaffed, as it seemed like only two people were managing the entire service. They appeared overwhelmed and constantly rushed, which affected the quality of service provided. If the restaurant was experiencing a high volume of customers, it should have had adequate staffing to ensure efficient service. To add to the frustration, the drinks took an unnecessarily long time to be served. Overall, the poor service experience left a sour taste in my mouth and detracted from what would have otherwise been an enjoyable dining experience. I hope that GBK management takes note of these issues and takes steps to improve the service quality at the Stratford location. Customers deserve better, especially from a reputable establishment like GBK.

Really disappointed I’ve been going to GBK for years and really cannot fault the food but the service in this branch is terrible I had to wait a long time to be seated when the restaurant was empty! I have to order at the till as o have dietary requirements this also took to long considering there was only one person in front of me I then waited far to long for my food and then had to ask for my drinks long after my food had arrived, when I wanted my drink refilled I had to resort to going to the bar myself! Poor service guys you need to do better!!!

Permanently lost a customer. I waited 20 minutes which had a queue of 10 people with the restaurant half empty, filled with dirty tables. I then had to queue again to order my food, which took another 20 minutes. The staff messed up my order which was as simple as it gets: just a burger with blue cheese and chips. The burger came overcooked. I had to bring it back to the kitchen myself and ask for a new one. The new one didn’t have the cheese on it. I didn’t get my drink so I went to the bar and asked for it myself. I got it in the end. The meal was pathetic. For £3 for a side of chips, I got about 10 chips, which have been cooked a looong time ago. I left the meal hungry. So many corners are cut with staffing, quality, the method of ordering and design. No wonder the Nando’s is packed and this isn’t. I’m never coming back. Waste of £11.50 and an hour of my time.

Sent me a promo voucher for a 50% food discount. T&C didn't tell anything about the locations where I could use it. So we came to the place, but I couldn't redeem the voucher neither on the web nor in the app. Then I was told that the voucher can't be used at this location. Awful experience and customer service. They spam you with the vouchers you can't use. Also, the venue wasn't busy but we waited for our food for about 40 minutes. Update: contacted them directly via email and didn't receive any response.

I ordered the rocketman burger and a bottle of coke on a sunday that wasnt too busy. I was really thirsty and the coke only arrived once the burger arrived. It wasnt even real coke either; it tasted too much like soda water. The burger arrived 25 mins after i ordered and it was not worth the £12 i paid for it by itself. It ultimately was just a beef patty, cheese and rocket with very minimal flavour to note. That was a waste of £15.60.

Horrifically bad service. So many other options. Never come here.

I used to go here years ago, but since then I have had Uber Eats deliver food from here on a some rare occasions. In the beginning, this place was generally quite good, with an open kind of setting and plenty of tables of various sizes available. I liked the moody and dull lighting, and it was fun to sit down and share a few peanuts or something. It is quite expensive to eat here and in recent years I have not been able to justify the expense, so I don’t eat here much now, but I used to enjoy that it wasn’t as busy as places like Nando’s, and one could just sit and relax with a bunch of friends and not be in a hurry to leave. Of course, it all depends on when you visit because I am sure there are times when it gets busy (such as the weekend), but on an ordinary weekday, this place has plenty of tables available. The place looks clean and well maintained, so one can relax and not worry about the place being filthy. As for the food, there is a good selection of burgers and they are cooked to taste (medium, well done etc), and there are also vegan options. The food is well cooked and pleasant but for the price, one cannot expect any less really. Having said that, I am disappointed that the buffalo burger is no longer available as it is a leaner meat, and somewhat healthier than the beef burgers they serve. That was my favourite burger, and it is disappointing that those seem to be off menu now. They have different types of fries as well, and I used to like their sweet potato ones, which were nice and crispy, and make a great change from the usual fare. Their milkshakes are worth trying because for my money, they beat a lot of similar offerings from other restaurants. While there are other restaurants in the centre, I think this offers a nice break and is tucked away neatly on the top floor, away from the bustle and bustle of other parts of the mall. Since most people probably visit the place occasionally, it is worth the money. I have not been in the actual restaurant for years, but I have ordered food from here on a few occasions using Uber Eats, as an occasional treat, and I must remark, the quality of the food is still high and their milkshakes are truly great. In the end, it is quite expensive for a burger joint and Stratford has no shortage of them. McDonalds is on the lower ground floor and is cheaper. The Burger King is in the old Stratford Mall right outside Westfield. There is also Wendy’s, KFC and another McDonalds at the Broadway, and although GBK offer premium burgers, I think the other restaurants beat them on price, so if you don’t have the money to spare, I think there are some good alternatives. I am cutting down on burgers and fries so for me, GBK is Ok for an occasional treat, but if you like burgers and fries more often, your wallet will thank you for choosing an alternative outlet for your burger fix. I think the premium Burger King Burgers give GBK a good run for its money because they are cheaper and l most as good, so be mindful of your options.

I'm sorry but this is absolutely the worst food i've ever received. One dry overcooked burger with no sauce, not a single slice of lettuce on some dry bread?! The salad I ordered separately was about 3 brown leaves of lettuce in a disgusting sauce. I'm honestly speechless.

The chocolate milkshake it’s messing?Why?

We had a large group and visited after a long time. Labeeb was awesome and took very good care of our group - he ensured food reached our table on time and followed up on all our needs - loved it!!

Milkshake but no straw, no sauce

Driver didn’t follow instructions had me walking around the building to find him, he was so late the food was cold

Chefs should learn how to cook meat. I ordered medium and got it well done. It wasn’t first time. Burgers taste pretty good but chefs definitely should improve cooking skills.

We have yet to have a bad meal here, even when on one visit our order was messed up it was still an enjoyable meal. The ordering system on the app works well and isn't over complicated, the staff work hard and my only complaint hence 1 star off was that the ladies loo was in less than good condition, probably because the staff are too busy elsewhere so not a complaint against them. We keep returning and hope when we move that there's one near where we are going.

Great burgers! Fantastic service!

The people in here was very friendly and service was on point! Highly recommended

This place was very good, I am not very fan of burgers but this place really match my expectations, Ajith and Rohith were the guys who served me, great service and great food, I will really recommend it

Was asked about allergies at the door, said sesame, decided what to eat and went to order before being told we couldn’t eat there because they use sesame in everything

Came here (Gbl Stratford city) with family. Been to many of these restaurants. This was by far the worst experience. 5pm and out of skinny fries. I asked the waiter as ordering on the app. He went to check with kitchen and then I had to go and find him, and he had forgotten to come and tell me it was out. Table for 6 people had 4 napkins and 3 forks. Food came before the drinks. Music intermittently very loud for no reason. My medium well burger was more than well done, my family were happy with theirs. Just generally poor all round and won’t come to this branch again.

Spacious place to chill and eat, love sweet potatoes fries and yummy burger. New dish Chicken wings is recommended. Cocktails are not impressed and quite simple presentation. Price is good👍

Dont waste your money. Was recommended GBK Westfield stratford so it was unfortunate that food was abismal possible worst I've ever had. Had a chicken burger, rings and chips. More grease than KFC meat tasted like reheated chicken and the thin fries were insipid and like chewing cardboard. The onion rings were half cooked at best. Better of having a Burger king or McDonalds and much cheaper and quality. Gourmet it is not.

Very long waiting time even if wasn't full. Had a hot glass for beers.

I had a birthday here and I LOVE it, delicious Korean fried chicken burger on special menu thing and even though there were at least 10 people at the party the service was still quick, but the lighting and the arrangement of seating doesn't match the atmosphere.

Tasty burgers with decent portion sizes. The new hot honey chicken wings were absolutely incredible! Service was lacking unfortunately.

Went with my mate but it wad really late so the place was quiet. Great food. Friendly staff and service. Only thing I speak for alot of members of rhe community, your prices are ridiculous, if anyone pays 13 pounds for a burger. Which tastes amazing by the way. It should come with chips atleast.. Would love to return but not for that price.. would love to know if your menu gets adjusted.. please share and like if you agree. Thanks. Great place overall, you should try it if you never been before. 👍

Emma our server was amazing, and the food was delicious. The food came quick and with the student discount meant that it was reasonably priced. Burger was amazing, sauces, service, everything! Would definetely come here again!

Good food and nice service. I loved the Korean burger .

Food cold. Took an hour and a bit from delivery.Poor

My first visit to Gourmet Burger Kitchen at Westfield,Stratford Good experience. Labeeb served us with great customer focus and very friendly. Fast delivery of food and enjoyed the visit.

was a good meal out and friendly service. food came quick and warm. the let down was all the salads in the birgers were not available - yet the price was not discounted or the missing items were not subtitued. on top of that adding jelepenos still incurred cost which put a downer on the experience

Went on the 24/12 and got food poisoning!!!! Never again!

Good burger place - service was quite quick. Just note that if you want the student discount, don't use the app (as the menu suggests) it doesn't work. You need to pay at the till and show your student card there.

I was appalled with the service I received here, I am a type 1 diabetic which means I can’t have sugary drinks only sugar free, I ordered a Coke Zero and sugar tested it when it arrived and it came back it had sugar in, I didn’t mind as mistakes happen and this is why I test my drinks, I politely went to the bar and apologised for being difficult, explained my situation and asking for a new drink to be made. The woman was rude and said that wasn’t what I ordered but she will make it for me this time, she then proceeded to make it in the same glass which I politely asked if she could not as this still had leftovers of the sugary drink, she seemed annoyed about this. She then poured me a new drink in a new glass and proceeded to say to me try it, I said I will just have to test it first and she said in an abrupt manner no taste it now and was forced to drink it. I’ve been in this situation many times and never had this sort of rude reaction, and I’m appalled that I was spoken to in such a manner in regards to a health condition.

Very nice staff but shame about the food. The burger is not fresh and definitely not freshly made. The chips are soggy and feels like stale. I wont go back there.

Food took ages coleslaw was off and mouldy food was horrible not like other gbk's

I went to GBK for a spot of food for my Dads birthday. The food took over an hour to initially arrive. After arriving we had to send back our food. My chicken was cold as well as my Dad and brothers chips and my onion rings. When I asked the staff about it they looked lost and really offered no support even after having to send back my food 3 times. Customers were arguing and the staff came off as really rude and amateur. This restaurant needs a real rethink and I will not be returning any time soon.

Excellent place for family and the service provide by the team were really good.

The order wasn't delivered and I still got charged and the delivery guy put it as delivered. Just eat refuse to refund money . Anyone else knows how to get my money back please let me know

I never received any order . Driver seems to be lost . He never came to my site at all . I have taken screen shots over the time period and he was never anywhere near to the delivery point . Can I request full refund ??

Burger was luke warm. Chunky chips OK. Sides of: truffle chips OK, wings OK, hallumi too salty. Boston lager was nice but not filled to top of pint glass, always annoying.

I always come here when in Westfield but today was a terrible experience. Waited over 20 minutes and had to ask waiter to bring drinks, literally arrived right after a food did. The waiter didn’t order an extra portion of fries so had to go back to the counter to get another portion. The food quality is lacking, feels like the ingredients are cheaper and the flavour is lacking. You guys had such a unique touch with the hei hei salt and monkey nuts, shame you got rid of it. Such a shame it’s gone downhill.

Queued to get in. No one came to seat anyone. Eventually guy at front went up to waiter and pointed out the loooong queue. Another water eventually seated them and wandered off. It was only half full inside. Been GBK before and really like the food but the service at this one is appalling.

I ordered the chicken burger which Ive had before and used to love it but it was tiny! Looks like a kiddies burger. Plus the chicken was overcooked and very dry

This place has gone rapidly downhill since Covid. First their blue cheese burger sauce turned rank now their milkshakes that cost £5.75 are more watery than a frijj shake. No one in here. No atmosphere. And slow service. I can’t see it lasting more than a year I won’t be going again. Which is a shame as I used to love it

Good lunchtime deals and always tasty burgers. Bit expensive to go at weekends or in the evening as you pay for the burger and chips separately.

They do good burgers. However, it feels like the size of the burgers have decreased whilst the price has only increased, which is a shame.

GBK used to be great. The extensive burger menu they used to have is now much smaller. The £7 lunch special isn't worth it - the burger is tiny and ours were overcooked. We weren't asked how we'd like our burgers cooked. The Garlic Mayo is awesome. Half price cocktails until 5pm are decent too - £4 for a cocktail is cheap, especially in London. As for atmosphere - the place was pretty empty; atmosphere was lacking.
