Honest Burgers Kings Cross in Islington

DO NOT GO IN HERE - there could be a food safety issue. Just been very sick from a burger I ate in there Saturday. I am vomiting and have the serious runs.. environmental health you need to go do a check asap!! And I’ve just seen another review on here to confirm somthing is wrong here.

I’ll start by saying that the service was good & staff were really nice. However after eating here I started to develop, chills, stomach cramps vomiting and diarrhoea. I am currently suffering with food poisoning. I came here with my date who is experiencing the exact same symptoms. At first I thought that we were just unlucky however I have seen some other reviews which have said the same which leads me to question the cleanliness of this branch. Very disappointing !

The portion is mostly fries and the burger is tiny. The following morning I felt terrible and had a headache before going to bed because of it.

Honest in name and in fact. The three stars evaluate all food, service and environment. If you take a fixed menu you can eat a decent sandwich without spending a lot, good not exceptional.....I would therefore say HONEST

Similar prices to five guys down the road. But much better quality and a proper dining experience, instead of the Happy Days style diner.

The Tribute burger is pretty tasty. If you want a refreshing drink order the homemade mint lemonade.

We ordered the month's special burgers which comes with fries. It's not the best burger I have had but was tasty enough. I just wished the pesto sauce has more flavour.

for the price, the quality is phenomenal. i loved the smash burger. great bread, amazing melty cheese and plump mayo, crispy and flavourful meat, and SUPER SWEET AND SOUR DILL PICKLES!!!!! SO GOOD!!!!! THANK YOU! the vegetarian side salad was also so flavorful and well-balanced, good spice and light dressing on fresh leafy greens, it pairs so well with a hamburger. and i love a cute herb on a fry, so the rosemary was great. the fries were really potato-y in the good way, with a delightful crispy outside. very happy with Honest :)!

Great burger, awful chips. Does the job when you just need to eat. That's all

Quick bite to eat, great burgers and fries.

Staff very good speciality burger is best burger I have ever had

Burgers were very good, convenient for KGX station, 5 min walk.

Always hits. Great vegan and gluten free options. Fresh beer, crispy salty fries. Loads of seating

I do like Honest Burger but the place was empty and we just wanted to sit by the window. Fair it was a 4 seat table and just the two of us but there were many other empty tables for four. Our request got refused not to mention it was one hour till closing on a weekday. I work in hospitality also and if the request such as this one is easy to provide we always go with it. Anyway… i love Camden Town Honest Burger, for me this was the first and the last time to go to King’s Cross Honest Burger. Not really because of the table thing. We will survive. But zero empathy or willingness to work on the face of the staff.

Really good burgers especially if you're vegan. It's a chain but it's really cool. :)

Came across this place by accident whilst staying in London. Very glad we went in! Food was absolutely divine. Staff were amazing. Thank you for a lovely evening. I would say I may have had the best burger of my life here (so far). 10/10

Very nice place to eat and spend time with your friends. Their chicken’s are halal. Highly recommend!!

The hamburger was very good. Also ask for chipotle mayo. It was a nice sauce too. Even Medium is extremely filling 🙏

It is by far the best hamburger I have ever eaten in my life. Even thinking about it again makes me salivate... haha Be sure to stop by when you visit King's Cross. It's just crazy.

We're regular visitors to Honest Burgers in various locations when on our travels, this was the first visit to this branch and we were impressed. Staff lovely as usual, busy on arrival but seated and served timeously, food excellent, prices competitive, handy location close to kings cross station, would visit again

What a piece of Smashed Burger I just ate with some freshly made potatoes. Children's menu at 7.50 pounds, the homemade lemonade is very good.

Very good 👍 I recommend it! We were a couple with a 15 year old teenage girl and after 20,000 steps during the day it was very comforting!

Always have a lovely experience here. The service is prompt, and the food always scrumptious. Excellent value for money.

Everyone was so kind. This was the best chicken wings I have ever ate. I insistly suggest this chicken wings. Burgers are fine.

Very nice restaurant, friendly and helpful staff.

Amazing food great service kind staff would come a second time

The humburgers are very good Nice and welcoming place Convenient to King's Cross

Good food, good for allergies but I’m also allergic to rice so even the gluten free bun wasn’t ideal. But enjoyed the food I did have and the staff were lovely and didn’t rush us

I can't believe Fives Guys is so busy when Honest Burgers is nearby. Great service, great burgers, great chips and you can also have a beer with it

Probably one of the best burger places I've ever been to. 1) 💯 The quality of the burgers: After speaking with one of the girls who served us (who I will also talk about later) she told us that they have their own meat supplier, that everything is gluten free, and that the products are supplied DAILY, that is, sauces, meat, bread, vegetables... THEY ALWAYS replenish it fresh. I would dare to say that it is one of the few burger restaurants where you can go on a Monday without fear of getting leftovers from Saturday. 2)👅 Very successful flavors: A hamburger is something that is difficult to surprise with, it is still a bread and meat, but the two I tried had their touch in the sauce, or in the accompaniments. HIGHLY ADVISED that you do not leave without trying the wings, they have an incredible flavor mix that you have never tried before. 3)🫂 The attention: The treatment we received as soon as we entered was 10 from ALL the girls there. But without a doubt, the girl who spoke Spanish made the difference. He treated us with great affection, explained to us where the meat came from, told us about the company, how the chain has grown in a short time... In general, someone that every employer would like to have on their staff. Thank you for everything and we wish you the best! 😊 4) 💵 The price: No burger exceeds £15, a drink at a good price (you can always order tap water), and also, if you register from the website they give you a discount of £5 when paying, so it is a price quite similar to that of any burger restaurant in Spain. Honestly, you have to go. Hope this review is helpful! Take care😉

Good burger, possibility of cooking the steak, and possibility of choosing the accompaniment (fries, salad, or cabbage). Vegetarian option a real plus.

Really kind service and tasty burger’s. A very good first stop while arriving in London.

If you already love what honest burgers offer this is one of the best locations. The interior design and atmosphere is really nice and looks more like a restaurant, the servers are very kind and attentive. £9.50 for a smashed cheeseburger with rosemary fries is one of my affordable gourmet burger favourites. A good place to go for a fun date.

Wrost staff I have ever seen in life

Went here with a colleague after finishing a job in London last night. We had limited time before trains home, and the staff were amazing at accommodating us and making sure that the food arrived in good time (without it feeling in any way rushed). The burgers were *sensational* - genuinely one of the best burgers i've ever had! I will definitely be back when I next have the opportunity - no doubt in my mind. 5*

Came in, the served was a younger kid who smelled (literaly, i am not being mean) and was super impatient and not caring. Would jump in and out trying to juggle multiple tasks i guess. The vegeterian options are very limited and vibe is dark (not in a good way) and not very cozy. I got tired of this place after 5 minutes, and didn't even bother ordering ant food

My girlfriend and I had one of our top 3 burger ever there, we had a great Time in this restaurant To all the future customers, you need to order the bacon gravy and deep your burger in it, you won’t regret it (Thanks for the old fashion hospitality, I’ll never Forget it)

always go here before I catch my train. The service has always been fabulous. The staff are really lovely! Saying that, I was there yesterday and had my order-to-go and they were a little stingy with the fries. I was surprised at how little there was in there when I got home. :(

Once again, Honest Burgers hits a home run! Love these guys. This is nice location near King’s X with some all star team members. Jasmine specifically provides fantastic device. She’s always so kind and full of energy. Thanks for the alway delicious burgers y’all!

The staff are very efficient and friendly. Delicious burger, of course ☺️

My family and I went recently to celebrate my nieces birthday . The staff were so sweet -singing Happy BD , put a candle in the burger and gave us all shots before we left . They were Great and made our visit there so enjoyable . Thanks so much .

The burgers are tasteless, but at least they're not gristly. The gravy is very good, but who puts gravy on a burger? Maybe just to mask the lack of taste. The prices are pretty reasonable for the location. Service is friendly. Vibe is a bit families waiting for trains.

Price performance fits! The fries are outstanding, the burger tastes great. Also a very cozy shop and nice staff!

As with any visit to London, a visit to Honest Burger is a must. Since we were heading towards Kingˋs Cross this year, we went to this restaurant this time. Seating on the ground floor and basement. Tried and tested menu and nice service. Recommendation!

Honestly? I’ve had better burgers in a Burger King… Good service but let down by the ‘formula’ food

Very good burger, the meat is good, the lemonade excellent

Delicious burgers and coleslaw! Serves quality meat in the burgers that you can taste. Fries are skin on and delicious.

Today at Honest Burger [Kings Cross], I experienced an unpleasant and disrespectful interaction. While trying to arrange seating for my family of four, a staff member (possibly the manager) publicly reprimanded me for moving a table, insisting I should have asked permission and stating I could only sit where they had predetermined. This confrontational and discourteous behavior, especially in front of my family, was completely unexpected and inappropriate. Such poor customer service significantly detracts from the Honest Burger brand reputation. It's unfortunate that this location's staff conduct is undermining what is otherwise a respected burger establishment. Based on this experience, I cannot recommend this particular branch to others.

One of the best vegan burgers I've ever had

Yasmine was absolutely amazing made our entire party feel at ease. It was really busy but Yasmine remained calm polite and super friendly. Food was really nice for our team Xmas lunch. Location was clean and welcoming.

Splendid! Top class place, the burgers taste perfect as “medium-well”. I believe the default option is cooked as a “medium-pink”. Good quantity of salt on the rosemary salted fries so you could really appreciate the flavours! The tap water came with ice and a slice of lemon which certainly adds brownie points. You won’t regret visiting….honest!

Pretty good smashburger but a bit uninspired with the toppings, good fries (huge portion), alright coleslaw (tiny portion) - so don't swap your fries out unless you're okay with that. The chilli burger with honest beef was really good, and actually spicy, try that Really nice onion rings (albeit pricey)

Good location but very loud (I know this can't be helped but it is worth noting) good value food but wine is fairly expensive. Staff polite and helpful, good variety of menu choices.

Nice place for a quick meal, delicious food and great service

I have tried practically all the chains in London, in my opinion this is the best for various aspects, the sandwich first is among the tastiest and most balanced, then the chips are made by them and finally the prices are much more competitive than other chains in London London

First meal after arriving in London The crispy yet chewy French fries, which I had never tasted in Korea, were really delicious and the combination with the mayonnaise was fantastic. What can I say about the hamburger, it’s so delicious. Because it was a weekday evening, there were a lot of people, but there was a place in the basement, so I was guided to the place and had a really delicious meal. The staff were very friendly, and I was especially grateful to the short woman who took our order in the basement for being considerate of our English skills.

On the first day of Christmas, my true love...took me to have a delicious burger at Honest Burger King's Cross! It was so good that we went back the next night for dinner, as well. The first night, I had the vegetarian fritter burger. It was well balanced, flavorful and interesting. The rosemary fries were definitely a food memory of London. The next evening, I tried the Plant burger. It was one of the best vegetarian burgers of my life. It was juicy and the flavors were once again well balanced. It was a classic combination of ingredients that hit every single mark. Everything was spot on. On the second evening, I also tried the onion rings and homemade lemonade. Both were good. Though, the onion rights were a tad greasy for my taste. But the batter was really yummy.

One of the best burger we've had in a very long time, and the chips were even better.

In my opinion the best hamburger chain ever. Both the meat and the bread were delicious. Good service. Honest prices

I had a burger with blue cheese and the 500ml carafe of red wine. It was excellent. The atmosphere was good for 4 o’clock on a weekday afternoon. The staff were friendly and professional. Had a lovely time. Would definitely recommend. 😊

Great burger and fries (or chips if you’re a local)! No complaints!

Honest burgers never disappoint! Great burger! The only thing I always miss is the local craft beer on tap. You either have Brooklyn on Tap, or local craft on cans.

The best burgers in town.... End of!!!!

Food always tastes great, drinks are lovely. Staff is very freidnly and attentive. Love coming here every time.

Service was slow but burger was good.

⭐⭐⭐⭐⭐ A fantastic experience at Honest Burgers King's Cross! What a gem of a place! The friendly staff made the visit even better. The food? Absolutely incredible! The onion rings were perfectly crispy, the burger was juicy and cooked to perfection, topped with fresh ingredients. And the rosemary fries? Simply irresistible and a unique touch. 🌟 Perfect for a quick bite or a casual dinner. A must-visit if you're nearby! 🍔✨ #HonestBurgers #KingsCross #BurgerLovers #FoodieFind

The burgers are excellent, the staff is friendly and welcoming. I will come back 😊 The waiter even thought of putting the payment terminal in French 😉

Anita was amazing. Customer service was outrageously good. Food great as always. ROL x

Amazing burgers. Man alive. I could have eaten three. Service great, drinks great, great pricepoint which will have me coming back when I'm in the area. Never tried an honest burger before but certainly will around the country after actually having one! Not to be missed.

Such a great burger, not much else to say!

Came in last minute with work colleagues! Anita severed us with insane speed and professionalism. Such a good time and great food 🤌

Anita is the one! service like never before. just come.

Amazing food, excellent quality, thoughtful service 👌 first visit today, will definitely revisit ❤️🙂

Great burgers. My new go to burger place.

We always enjoy coming to this Honest Burgers. Last time, we sat downstairs and it was a bit too noisy, but the first level is cozy and perfect for a more romantic vibe. The food was as great as always! Tip: Skip the onion rings—they weren’t great.

Very good hamburger and fries! Fun Waitress !

I am a massive fan of honest burgers! Particularly this branch as its the only one I've tried and I've been 5 times in the last 2 months. I've had the double smash burger twice, that was lush. The chilli burger twice, loved it.. the second time I asked for the jalapeños to be on the side as it made the burger a bun a tad soggy.. and the most recent visit I had the actual Honest Burger and was not disappointed at all. But burgers aside... it's all about the rosemary fries!! My God they're just the best fries in town. Even my fussy eating son loves them and that's saying something! The staff are always welcoming even on a busy Friday evening.

Lovely place, tasty burgers with bufallo sauce

The music is a little too loud and the onion rings "swim" in fat, but everything else is excellent. More than satisfied. 😊

Great service, tasty hamburger.

One of the best burgers I've ever eaten. Wonderful staff and possibility to order delicious veg burgers.

Love you guys all of yo best stuff and best behaviour 100% recommending it go and enjoy the food.

Went here on Friday night, was immediately seated even though the restaurant was busy. The service was fast and precise and the food was delicious. And our server Ruth was lovely, she handled my partner's dairy allergy expertly. she was very curious about how far we had come and was a lovely person to talk to. Overall flawless experience, will definitely come again if in the area.

Very good burgers and kid friendly, but be careful they do not offer dessert or coffee on the menu.

A stone's throw from King's Cross and St. Pancras stations, it offers an informal and welcoming environment. Delicious food, with vegetarian and gluten-free options (food cooked separately), honest prices. Praise for even letting my little dog in! Super recommended!

Our last Honest before our next trip to London. Friendly and smiling team, exquisite cuisine. One of the best burger chains we know.

The service was almost instant and they came to check up on us multiple times Best burger I ever had Everyone was very happy and kind The toilets were immaculate and the table was clear too.

We visited late Friday evening and the waitress was incredibly rude to us. We decided to leave the restaurant, it was that bad. A shame as the food is usually good.

Tasty burgers and delicious fries.

I had the smashed burger. It was good. Sorry I did a wrong review.

Delicious burgers and wings at reasonable prices! Top!

Fantastic visit this time (I’d left a poor review in June 2024 as I’d felt it had taken a downturn ) this time it was friendly it was CLEAN the gf pesto burger (you can have it with no pesto it’s great!) rosemary fries gf onion rings Coca Cola. Come on what’s not to love! Will def go again on next trip

Honest is a great name for this place as the burgers are just that. Good service from the young lady that served us.

Absolutely elite burger - three cheese medley chicken burger! But even more elite staff!!! Lovely lovely atmosphere and energy :)
