Gourmet Burger Kitchen (GBK) in Lambeth - Phone Number, Reservations, Reviews

Great place for a typical GBK burger You need to try the milkshake too The interiors need a bit of refurbishment though but it's still a nice place nevertheless

While the food at this restaurant was commendable, the service was nothing short of atrocious. Upon entering, I was left standing without any greeting or assistance, despite the restaurant being nearly empty. Instead of doing their jobs, both waitresses were glued to their phones behind the cashier (check your CCTV if you don't believe me around 5pm on Tuesday 13th Aug). Anyway when I was finally seated, a young waitress in an Adidas top approached with an obvious bad attitude. Her rudeness and sarcasm were apparent when I asked a simple question about whether my chips would come with ketchup and mayonnaise or if there was an additional charge. The menu mentioned a fee for a special type of mayonnaise, and I wanted clarification. Her reaction made it clear that she not only dislikes her job but also has no interest in providing decent service. It’s baffling how someone with such a poor attitude was hired in the first place. Whoever conducted her interview clearly failed to assess her suitability for a customer-facing role. This experience has ensured that I won't be returning, despite the quality of the food. The management seriously needs to reevaluate their hiring and training practices if they want to keep customers coming back.

The food is fresh and of high quality as well as having a great flavour. There are also options for vegetarian and vegan food. The staff is polite, smiling, kind and attentive to your needs. The place is welcoming.

Awful service with unhelpful staff. After asking them to change us to another table because it was cold at the entrance, they refused to accommodate us. Bearing in mind that the restaurant must have around 25-30 tables and only two were occupied, it really seems that they couldn't care less about their customers. On top of that, when ordering cider from their 'incredible' cider and beer section on the menu I got a 'we don't have cider', and when asking for any alternative for celiacs I received no answer. Plus a burguer for £13 without any chips or salad!! You better off going to MC Donald's and get the same service for half the price.

Amazing dining experience the food was delicious and cooked perfectly. The cleanliness of this restaurant was also amazing. In particular Emma made the experience one to remember as she always had a smile of her face and was friendly, and a super nice person. Her kid friendless and her customer service is brilliant great shout out to her.

The burgers were okay. The staff seemed to have mixed up our orders and the "well done" patty arrived pink inside, while another "medium well" patty was fully cooked.

One of the most approachable hamburgers in London, simple and tasty.

My son and I ate at the Waterloo location of Gourmet Burger Kitchen in July 2024. Fron the outside, it didn't look particularly impressive, or even open, but inside the staff were friendly and the food was awesome. My son enjoyed his vegetarian burger (although it wasn't his most favorite in the UK, it was good), and the Korean chicken sandwich was one of the best chicken sandwiches I have ever eaten. I was actually shocked to realize that GBK is a chain because the sandwich was that good. Sides do need to be ordered separately (my son and I split an order if fries). I definitely recommend this place for a sandwich and a pint of Britiah pale ale.

I ordered a vegan burger (California?) and it was fine, wasn’t spiced very well so it didn’t really impress. Milkshake was very good tho. For this price it could be definitely much better. Service very polite.

Excellent food, great friendly service.

Good customer service Food wassss dam tasty

It's good. Don't get me wrong but it's just overpriced. Foods decent. 4 stars.

Terrible service. After an hour wait, they messed up the order. Manager couldn’t care less. We just left and he wasn’t even apologetic.

The GBK on Waterloo road was amazing, the service was so brilliant and the staff were so pleasant and helpful. Especially the asian gentleman with the glasses. He was so pleasant!!! Thank you so much GBK I will definitely eat there again!!!!

This is a massive improvement on what me and my partner experienced last year. I was greeted by the Manager who actually let us choose our seats (something the previous manager didn’t allow for some reason) but the food was flavoursome I actually finished my partners fries that says a lot. But this is how I remember GBK back in day when it was in Clapham Common 😍😍

i would like to say the man obe with glasses is a excellent staff. i like his service . will like to come again

I ordered the classic chicken burger and Obe the manager really took care of my order personally and more than that scrumptious burger, it was his service that elevated my experience at GBK .

Been to gbk Waterloo on 2 different occasions on both occasions the manager (with glasses) was present and greeted us as soon as we entered the establishment he was very welcoming and made our time at gbk very warming thw food and service was very good thw only reason I haven't given 5 stars as there are a couple of things that need to be improved

This place offers decent burgers. I didn't find them to be especially yummy, but it definitely was a decent burger.

So disappointing Ordered blue cheese burger (medium rare) and a bacon and cheese burger (medium) When the burgers arrived the beef patties was in the wrong burgers. I believe they accidentally mixed the two beef burgers up when they where making up the burger Requested the medium to be redone to medium rare and this then came back bloody. I brought this up to the manager and he was insistent that this is standard of their medium rare ( even although the medium rare initially was cooked perfectly) He refused to make another burger for me and did not even offer the chicken options. I found him very unprofessional, uncourteous and impolite. Just disappointed that they got it wrong in the first place as the first cooking was done perfectly just in the wrong burger. Will not be visiting again

Friendly staff and good burgers. The soft drink list could be expanded a bit to cater to kids that dont drink Coca Cola😉

Ordered burgers with fries. Food was very good. The server was friendly and helpful.

Great atmosphere. Really enjoyed the food 🤩. Kamil the waiter was always quick and profession we definitely will back . Thanks

Great service and quality of burgers, we recommend

Staff are fantastic ! Manager is a vibe ! Fantastic food !

Food delivered quickly, great service, especially miss Paulina. Highly recommend.

I've only got Amazin things to say about this restaurant all the staff are amazing and burgers are amazing too thanks for everything, also thanks for being so kind to your delivery drivers thanks guys Fabio A

Poor Service need to be improved 👎🏻

Lovely place and staff ♥️ and amazing food. Will be back.

Excessive westting Time Not good response from the female staff from your kitchen...Sorry..I am not happy

Came in for the lunchtime burger and fries offer. I swear burgers are getting smaller. The burger itself was a little overcooked. The fries are tiny. It was basic and tasted okay. Service itself was good and speedy.

Food was great but service not the best. Inattentive staff which I would appreciate if it was busy but on a Tuesday night it was pretty quiet. I have been here before and it has been okay so I guess it depends on when you go.

Excellent service from the manager. He was excellent

I don’t usually take time out of my day to leave reviews, but had to make an exception for the “meal” we have just been served at GBK Waterloo. We ordered strips and several sides off the menu only to be told some time later that the strips had run out and they could only provide wings. When the food came they got the order wrong and we had to return some parts. My truffle fries were absolutely swimming in sauce, I could barely see the fries and the coleslaw was a bowl of dry diced veg!!!! I’m no culinary master but I’m pretty certain it should have some moisture content. The chicken wings were the WORST IVE EVER HAD!!!! Greasy as hell, still pink in parts and several of them had strange rubber like veins flapping around. Neither my wife or I could stomach a single bite. On top of all this they then tried to charge us for extra sides we never ordered and one of the “free” milkshakes we had despite being told by the waitress that they would be free using the app. 10 mins and lots of huffing and puffing by the manager and we still felt violated for having to pay a single penny. Do yourself a favor, avoid this place like the plague. (Praying we aren’t sat on the toilet all night)!!!!!!!!

Big fan of this GBK - the food is nice and staff generally friendly. Decent discount with the Tastecard.

All the way from Germany. Insane tasting Burgers. Had the taxidriver and the hot honey wings. Sauce was insane. For a german… a bit expensive but Great!

Always love gbk, great quality and consistent across all locations! Well worth a stop. Service is super friendly as well which always helps.

Lovely customer great service Divene food Highly recommend

Delicious burger and onion rings. Very nice service.

Decent food, not my cup of tea but the qaulity was good, i say flavour is subjective, so its not really fair to judge just on flavour. The staff have a strong accent, like german or something so i had to ask them to repeat every sentence because i truely couldn’t understand them the first time, and the atmosphere is pretty cool, probably the best thing about it.

The best burger I ever had. Was cooked perfectly. The chef that cooked it needs a raise. Will come again

Everything is fine and the food is really good

Fantastic family burger meal out last night, before a special treat West End show. We just love GBK. Not been for a while, and I’m not a frequent reviewer, but GBK Waterloo smashed the food and service yesterday. We were looked after by Aguilero (spelling?) the manager, who was super friendly - but not OTT - and gave helpful explanations for several of GBK’s more unusual sauces. Our burgers and a chicken dish were cooked to perfection. Great food, perfect service and lovely shakes. The Malbec was pretty decent too. Great team delivery. Many thanks🙌

Good burgers, fries and great service.

It was delicious, the staff was friendly, and the store was spacious!

I cannot have dairy of soya, so I asked about what was available for me on the menu - so I was told to get the chicken burger but without the bun,- naked which comes with salad and slaw, then I was told I also cannot have the slaw and also cannot have the fries. So all I had was a sad looking piece of thin chciken and some old looking lettuce leaves - no other salad just some leaves and I was charged £10.50 for this dish.

Food and staff were phenomenal but the place smelled a bit bad I got used to it quickly though it must be a mop and/or washing cloth related smell

10/10. The staff couldnt have done more for us ( Paulina and chef Dawid) Place is spotlessly clean. Will deffo return the next time I am in London. Highly recommended 👌

Great service and friendly staff, try the onion rings!

Food was amazing! The Capler RD Cider would highly recommend! The onion rings were to die for!!! Definitely get the garlic mayo sauce!

First time in London and went to this restaurant by chance. The food was very good and the service was very friendly. From the outside you would never think that you can eat extremely well there. Would go again and again. Greetings from Zurich

The staff here are amazing! So kind and made us feel very welcome. The food was delicious, exactly what we were looking for. Service was quick and we had a nice meal there. Would definitely go back again, highly recommend!

Easy 5*. This place ticks every single box. Nice ambience and decor. Tasty food, especially the truffle fries. Fair price. Friendly service. One minor detail that I'll ignore this time around, please fix and improve your loo. It's also part of the customer experience. Don't take it for granted! Good job.

Brilliant place, lovely and friendly service, perfect for children and value for money in Central London

Very tasty burgers, but it is debatable whether they’re worth the steep price considering the size. Costs about £12-20 pound for a single burger excluding sides.

Tried out the lunch deal and ordered the chicken burger and skinny fries. Chicken was actually a decent chunk and moist, but the batter was a let down, it was too thick. Fries were nice and crispy. I also had the chicken wings and vegan milkshake. Chicken wings was moist and batter was crunchy but found bits of the batter chewy and hard… Loved the vegan milkshake, creamy and you wouldn’t of thought it was vegan. Service was friendly and efficient.

A lunch time deal worth going to lunch for! As always gbk fries are on point!

Excellent Burgers and Sides! We were very impressed by the tasty sauces!

We loved the food and the staff is great especially Gui. Thankyou

really poor experience at the start as someone (who i believe is the general manager) told us we could have a booth if we waited for 20 minutes but almost an hour passed and they completely forgot about us. when we proceeded to ask him about our table he said this is our table and ignored us after. very disappointed with this but we had a very good experience with our waiter shadab who was attentive to our concerns and very sympathetic - he turned our evening around after we had a poor experience initially so we thank him for that.

Nothing to distinguish this place from any other burger joint. The food taste fine. Grilled halloumi cheese portion was quite small. Fries weren’t really salty. Table was quite wet from previous wiping when we were sat down. The waitress proactively brought some drawing and coloring pens for our young daughter, which was nice.

Always love the burgers and milkshakes here

I love Burgers and this place has the best American Burgers. They always get it right 😋✅

It was a nice burger with polite staff but quite pricey (20 quid for burger, fries and small coke). Then again this is London, so it's not hugely surprising

The waitress Luisa was very nice , good service and all staf very friendly...I will back again

Good burger and sweet potatoe fries - Great service team!

Best gourmet burger in waterloo

Po celodení konferenci a pak velmi dlouhé procházce přes Londýn, byl toto nejlepší burger který jsem mohl mít. Ta chuť byla báječná. Bylo to ze speciální nabídky a opravdu to bylo skvěle udělané.

Very attentive staff, good food, can recommend

Not sure why you would put a seal on a bag that still has MASSIVE GAPS down each side so really not worth it in terms of making it tamper proof. I found motor oil!? Or dirt!? On a chips bag that looked like it had seen better days. The other chips, NOT THERE. No way of knowing who’s at fault as again the bag was not SECURE with the health and safety of the meal in mind. When will restaurants just implement this SIMPLE procedure consistently? I’m sure it makes no odds to your company but I won’t spend money in this place ever again. When you feel unable to enjoy or even eat the meal you paid for, because your not sure if your order has been tampered with is upsetting and I was left hungry. Really disappointed as care and freshness has in the past been satisfactory. Really disappointed.

Primeiro é excelente hambúrguer que comi in Londres. Garçons muito simpáticos e amigáveis

Lugar maravilhoso, com recepção, e comida bem deliciosa. Ambiente agradável e tudo muito bem servido.

Great service, really friendly waiter and incredible burgers!!!

Nie mam uwag. Wbijać i się nie zastanawiać!

De las mejores hamburguesas que hemos probado y las patatas tremendas tambien

A welcoming place with ok burgers but good milkshakes and fries. Went here for a casual meeting. We were greeted and seated and the staff were friendly. Orders were taken in good time and the food didn’t take too long to be cooked. We felt that the chicken burger was a little bit undercooked and they gave us a refund. The cheeseburger ordered by my friend was ok with fresh salad inside and the fries, rum drinks and milkshake were great. They provide ketchup and mayo without asking which I thought was a nice touch. We didn’t want to complain about the chicken burger but when we were checked on about how the food was we did say about the burger and they offered a refund. Generally it was an ok experience. The staff do try and are smiley. An average spot for a burger

Very nice Burger and great service. I will be back!

Burger chain with a decent menu. Well thought out dishes for every taste. Good quality food, fresh ingredients and generous portions.

The place was not bad actually. Service was also ideal, waiters and waitresses kept eye on customer’s need and very willing to help. I found many families chose this place for a warm and cozy gathering. Order was efficient and clear. I like the skin-on fries very much, especially when it was served right from the fried pot!!! Could not resist the hot chips However, the Korean BBQ chicken burger did not meet expectation. Meat was large indeed, but mostly flour skin making it too greasy and dry. The sauce wasn’t that korean either And was quite annoyed that fruit flies kept flying around all the time. Couldn’t finish my burger when one stopped by and stuck in my burger mayonnaise...

Great food, lovely staff, excellent milkshakes. Not much more to say

American (Texan) Traveler in London Opinion: Delicious burgers served in a clean establishment. It was a great lunch.

I did not enjoy their burgers however staff are amazing and polite and very hospitable for this I would return

The special burger-Jerk was absolutely delicious. Juicy and tasty chicken . Salsa and homeslaw combined yummy. Thank you chefs . French fries with Cajun seasoning - have highly recommended Service fantastic - quick,efficient just amazing.Thank you Michael and Naomi 😊. I will be back very soon

friendly atmosphere and efficient staff

Unfreundliches Personal Essen gut und schmeckt gut.kommt alles schnelles

Great choice for vegans and vegetarians, love Beyond Burgers and the chunky chips are tasty and hot. My bugbear is cold food! My partner is addicted to GBK at the minute. Love that there are comfy booths and you’re left alone to eat in peace without floor sweepers disturbing you like in other fast food restaurants. Obviously a bit pricier but you get what you pay for.

Went there on a whim after a theatre show, was quiet when we got there (table for two) so we didn't have to wait to be seated. Food was served in good time. Looked and tasted lovely. Both myself and son left STUFFED 😋.

Nice restaurant. The food and service was good. The burgers were delicious and the milkshakes were really really good.

Chips cooked in old oil as you could see the black small grains from old oil over the first made worse that they where hollow. One waitress super polite the one who took the order was short with us and abrupt. The food was not great. We traveled in as GBK was our fav for years and not had it since 2019 so pre covid and have to say this will be our last

Bester Burger, Bester Service. Sehr gutes Kindermenü. Patty auf den Punkt 👍

The best burguer and service in London

The best burguer and service in Waterloo region.

직원분은 무척 친절해요 그런데 고기가 많이 타서 나와서 아쉬웠습니다

The burger was good but the waitress was extremely rude. I wouldn't come again tbh.

Amazing trial ice coffee. Thank you for your service Aguinaldo (:

Food was horrible. I paid £10 for a burger £3 for a J20 £6 for a milkshake. Absolutely horrible. The Milkshake was the only thing that wasn't bad. Also £20 wasted. Never going again. Burger had no taste what so ever

We have had a horrendous experience, the waiter was very rude and dismissive. We felt unwelcome and uncomfortable.

Excellent burgers, friendly staff and fast service. Definitely coming back

Wonderful ambience and friendly staffs. Makes the experience pleasant.

We had a lovely meal at GBK, but the service was exceptional, Marta was a great host and nothing was too much bother! A true credit to GBK 😊
