Flat Iron Kings Cross in Islington

The food was truly excellent! The triple cheese was a real treat for me! The waitress assigned to our table was really kind. She made an effort to speak softly so we could communicate in English without difficulty.

The food was reasonably good. We left upset because they didn't even give us a second to check the bill, which they were eager to clear. We paid the optional tip (about six pounds), which we would have considered whether or not to give, and how much, had we been given the chance. It was awkward.

We arrived on Sunday evening as a party of 6 hoping to be able to be accommodated for Dinner. The front of house staff were very friendly and managed to find us a great table. The food was fantastic and the chips were delicious as was the steak. Service was quick and efficient. I will definitely be going back.

Unbelievable kindness and great service. Definitely the best in the UK.

Very good atmosphere, the service was impeccable and the food really good!

A very successful meal. From the very appealing ambiance to the excellent service, to the food itself. The concept is great, and the steak was so delicious. We'll be back.

Booking is a must at Flat Iron as they get super busy. Very simple menu, but what's more simple than a great steak with delicious accompaniments? I love the beef dripping popcorn to begin & the vanilla cone to go on the way out - both included with the menu. Amazing value, brilliant Team & service & fun atmosphere, the perfect evening bite when in London for a night. Highly recommended!

Got the steak, mash and mac-n-cheese. Was all very delicious, will be coming back!

Delicious steak and side dishes! The service is very friendly. You get a free bottle of water, popcorn, and ice cream. We had a great stay and highly recommend the restaurant. The experience is something special. The ice cream at the end was especially delicious. Thank you for everything! Unfortunately, the air conditioning in the basement was a bit too strong and cold. (Visit in March 2025)

Fantastic meal - perfectly cooked meat to how I'd asked, the sides I could have eaten a whole bowl of (even my partner who's not the biggest fan of greens went back for seconds on the spinach) and the passion fruit cocktail we amazing. If I weren't so full I'd have wanted seconds.

Classy flat iron dish, in general ok

amazing experience, great food !! mathias was super nice !!

Amazing place and service especially Mathias

Had a beautiful Cornish pichana. Mac and cheese 10/10 as usual.

The meat and beer are delicious for the price! It was a ray of light among the disappointing British food :)

As always, Flat Iron is the best!! Ordered 2 medium rare Flat Iron Steaks, with chips and the aubergine dish for sides. I tried the aubergine for the first time - definitely will be getting that from now on 🤭. Saved the ice cream token for the future.

Vadim was our server and he was beyond expectations, giving helpful advice and tips to make a meal better, smiling. Will come again.

Attentive staff. Doo value food. Good prices. Calm ladiback atmosphere. No pretense

The steak with the highest CP value in the UK. The tenderness of the meat is fresh and the side dishes are all delicious in high-end restaurants. The ice cream after the meal is very delicious.

Very charming restaurant and good food. The service was very friendly. The fries could use more salt. We'll be back!

The restaurant offers a very nice and pleasant atmosphere. It is stylishly furnished and the staff is very friendly and accommodating. We both had the flat iron steak with fries. It was perfectly fried and super tasty. We'd love to come back!

I recently dined at Flat Iron Kings Cross and had a memorable experience. The restaurant's interior is stylish and spacious, featuring bare-brick walls, reclaimed wooden furniture, and ambient lighting that creates a cozy atmosphere.

Great steakhouse with very reasonable prices for London. The burger was especially good. The complementary ice creams at the end are a nice touch.

If you're a meat lover, Flat Iron is an absolute must-visit. It truly does not disappoint. I tried the Picanha, and it was delicious!! The ambiance is warm and welcoming, and the staff is exceptionally friendly and always ensuring that guests feel comfortable and well cared for.

"Great dining experience ! The dishes was prepared to perfection, and the service was attentive and friendly. Cozy atmosphere. Will definitely return!"

Steak is mostly the original menu (there are a couple of options for Wagyu and other cuts), and we ordered eggplant gratin to share. The meat itself was well seasoned, but I think it would be good to order a sauce or two to share. The gratin was a little salty.

This is so unique in my list, ambiance is so good, especially the team is very kind and helpful..

Very good food. Friendly staff!

I used to be a big fan of Flat Iron and would visit regularly, but unfortunately, my last few experiences have been quite disappointing. The meat has become excessively oily, which takes away from the flavor, and overall, the quality has noticeably declined. It’s disappointing to see such a drop in standards, especially since this was once one of my go-to spots. Sadly, after multiple visits with the same issues, I don’t think I’ll be coming back anytime soon.

Can’t review the food because I was not able to order. Service is absolute rubbish. Good luck getting anything to eat here

We ate the most typical dish of the place, their Steak accompanied by a portion, it is an acceptable meat at a good price. Nice touch of popcorn upon arrival and ice cream after paying.

This has to be one of the best steaks I've ever had! The service was phenomenal!!

This was just the best steak Ive ever had! The server, a young man named Rocco knew exactly everything I asked about. I wanted to try the Wagyu beef and by his recommendation I selected the hangar steak. The flavor is still on my tounge, a day later. And the mash was amazing too, I would go there just for the mash! My favourite steak house in London, by a mile!

Delicious food, amazing service, great atmosphere and free popcorn & ice-cream. Had a great time, highly recommend.

We had a mixed experience with our service initially but Dominique turned it all around and was great! Good food too.

Food was lovely - beautifully cooked. Rocco was brilliant, really knew his stuff and recommended an incredible steak.

Super service and food even better ! Will defo be back !

All round excellent and Natalia was a great host :)

A cost-effective steakhouse!!😁 It was actually neater to eat with salt rather than ordering sauce! Above all, the best ice cream restaurant~^^

A restaurant with a wonderful atmosphere and a very juicy and perfectly cooked steak!! On top of that, the detail of the popcorn when you arrive and the ice cream when you leave seems wonderful to me to top off a good dinner!! 100% recommended!!

Just walked out of Flat Iron, and I’m absolutely happy! This place is a true paradise for steak lovers. The meat was perfect—tender, juicy, and full of flavor. I paired it with mashed potatoes and creamy spinach, and it was simply incredible! The atmosphere at Flat Iron is very cozy, with a stylish interior that’s elegant but not over the top. The service is top-notch—staff are attentive, friendly, and efficient, even when the place is busy. And the best part? The price-to-quality ratio is amazing. You’d have to pay much more for a steak of this quality elsewhere. If you love a good steak, this is the place to be! I’m already planning my next visit. ♥️♥️♥️

Be sure to try the truffle macaroni cheese

The steaks are delicious and the staff are friendly. I plan to visit again.

First time at flat iron, great food and service. Free ice cream was a nice treat

This place never disappoints. Usually go for late lunch...early evening then there is usually no wait. Treated ourselves to the wagu flat iron which was delicious with their fab chips and creamed spinach...it's just the best for a treat. Thank you to our waitress for my special ice cream.

I had dinner there, and the food was so good. I liked the apple mocktail

It was a great experience - the food was amazing - perfectly grilled steak, various and incredibly delicious sides - can’t say which one I loved the most because they were all sooo tasty - the truffle macaroni cheese, the crispy bone marrow garlic mash, and the roast aubergine! And the ice cream at the end was cherry on the cake:) The staff were brilliant as well!

Everything was perfect! The food was delicious - loved the steak and the chips. The ice cream at the end was a nice bonus. The staff were lovely and welcoming. Very warm and cozy atmosphere!

I had such high hopes , but it was disappointing. Nice sides, but I asked for medium rare and got completely raw steak in the middle for the wagu. It was also too salty and just not enjoyable :( rude staff too!

It was really delicious. Until the last ice cream. This is the first time I've eaten something so delicious in England.

I went to have lunch before boarding the Eurostar from London to Paris. We recommend that you make a reservation in advance. I was thinking of leaving my suitcase in the storage room, but the staff kindly put it in a place where I could see it. Since we are a family of 5, we ordered a variety of meats, and they were all good. (Personally, I liked the rare version a little better. I also ordered spinach, stir-fried eggplant, and macaroni as side dishes, but the portions were so much larger than expected that the 5 of us couldn't eat them all.) When you finish your meal, the table is cleared, payment is completed at your seat, and a miniature knife is given to you. You can take it with you or replace it with ice cream. We ate it with ice cream and it tasted good and was worth at least 5 pounds. I am ending my trip to London on a good note~

Great value and the tastiest steak in London. Always a winner in our family and makes a change from all that chicken

The tastiest and best value steak in London. Always a winner with the family and makes a nice change from the usual chicken

Steak is so-so, service is pretty good

Booked in here with my partner for my birthday, staff were very polite and helpful, they supply you with free water and beef infused popcorn while you order, my partner had the Iron Flat Steak while I had the Truffle Burger, my partner adored her steak, while I've admittedly had better burgers at cheaper prices, that doesn't make the food itself bad by any stretch, just lead to a minor disappointment. Afterwards, unknown to either of us, the staff brought out some ice-cream in a glass flute/bowl with choc shavings and a candle in it, wishing me a happy birthday, which was just a lovely little addition to the evening, we were then given tokens for an ice-cream on the way out, all of this was free of charge as well, we ended up buying ourselves the little butcher knifes that the sell to support them. Would easily go again next time I'm in London and might try a steak myself after how good my partner said it was.

Another wonderful visit to the Flat Iron chain. We went for two steaks that were cooked perfectly and were delicious! No sauce needed as it was tasty on its own. The burger was incredible! Three cheese burger with pickles was very tasty. The mash to go with the steak was super yummy and a different taste to the regular mash. The touch of providing popcorn before the meal and the ice cream afterwards is very thoughtful. This location was not ideal for us but it was the only one that had availability on Sat for dinner at a reasonable time. It is very popular so I would recommend booking in advance. We booked a week or so in advance. We arrived 5 minutes before our booking time and we had to wait for our table to be ready for a bit. But it was worth the wait. Restaurant was clean and cozy.

I'm gonna be as honest as I can be... Service... really good!! Nice deco which makes you feel very comfortable, however... about food,I ordered one of the two specials they had on the board which was 'wagyu skirt' £23 200gm cos the other one was sold out.I was very excited about trying for the first time this kind of Beef,they brought it very quickly as it looked to me they have plenty of staff in the kitchen as I was sitting right next to it. First bite I had didn't really impressed me at all because the beef wasn't tender at all and flavour wise nothing to write home about,Soon after which I believe was a person in charge asked me how was it and I said to her ...let me be honest,I was expecting the beef to be much more tender as is a chef's recommendation,she immediately apologized about it and she took it back to the kitchen to replace it for another one after having a word with one of the chefs.Again, very quickly another one arrived to my table which was at least more tender but similar flavour, maybe I had too high expectations about this place after seeing some impressive reviews on social media.Will I come back?...I don't think so,I think there are better steak houses out there .Something it's funny to me it's about people mentioning how good is to have some popcorn on the table while you're waiting for your food,as it was a really great treat from them, that's not relevant to me as well as a free ice cream they offered you at the end of the dinner which has to be taken away.It's something really appreciated don't get me wrong but the food your having it's the most important thing.Another thing I forgot to say it's about the very few choices you have on the menu which makes you expect much better quality every single dish you order.

Flat Iron Kings Cross is a great spot for steak lovers. The food is simple but delicious.The service is friendly, and the atmosphere is cozy, making it a nice place to relax. Prices are reasonable for the quality, though it can get busy, so expect a bit of a wait. Overall, a solid choice for a tasty and satisfying meal.

The food was excellent and so was the service.

We had an amazing experience ad this restaurant. The staff truly makes you feel at home!! Christian listened to our needs and ensured we had the best experience. The food is exceptional, each dish is carefully prepared, and the ambiance is cozy and welcoming!

Great atmosphere, lovely service.

Great steak and atmosphere, friendly staff and quick service.

Relaxed, cool atmosphere, intimate space but still has plenty of room for larger groups. A haven from the chaos of King’s Cross. Food was delicious, service was really friendly and attentive. We really appreciated the touch of having a free icecream at the end despite it being sub zero temperatures outside!

The food was delicious, and all the staff were incredibly hospitable and friendly. We were provided with free popcorn and a jug of water (as well as the drinks we ordered), and the steak was cooked just as I had requested perfectly. It was absolutely divine, and the beef dripping cooked chips were some of the tastiest I have ever had. Instead of a normal knife, we were given a mini butcher knife (albeit not as sharp as a proper one) which was super cute! We ended up purchasing two of them to take home too. When booking, I had stated it was my partners birthday, and they surprised us with a bowl of ice cream with a candle and wished him a happy birthday, which was a lovely touch. The atmosphere of the restaurant was lovely and calm too. Absolutely intend to come again.

I have been to several locations around London and am not ever disappointed! I go to one of their locations every time I am in town.

The food is good not bad but definitely not a meal size. I thought I made a mistake and ordered from a kids menu Staff are very friendly and welcoming though, washrooms needs more cleaning plz Not the best smell when you come in ( it’s like a rotten cheese) It’s pricey for that small portion

Food is great to taste a good steak, but definitely not a meal size. Staff very friendly. Not the best smell when you come in. Will we comeback. Probably not.

Great dinner and lovely service (Carlos)

I had my steak well done, chips were excellent. Bill was a bit confusing though, it said optional but, please who is going to say no to a £5 tip for staff. And then, this is new, 20p for charity, optional again but had no clue. Checked the charities and they are charities I would support anyway.

Food was amazing, and even better service thanks to Carlos. He was very personable and friendly, and seems like a very good asset to your team. Will defo visit again

Good steaking meal in a wooden interior vibe

Limited menu, but very good . Not overly expensive.

Food is lovely and the attention and service from Pip was perfect.

First time here and a Sunday evening. The place was bustling they managed to squeeze me in. Menu is deliberately limited. The free popcorn is a nice touch. I had the steak with chips. Steak was cooked spot on and was very tasty. The chips tasted so nice being cooked in beef dripping. I ordered bernaise sauce on the side. Slightly disappointingly tiny pot of sauce. I was expecting enough to be able to pour it on my steak. Service was efficient. I’d definitely come back when in the area.

My new favorite place! Cosy, superb and fast service. Perfectly cooked meat and very good sides. The icing on the cake was the ice cream that was included on the way out.

Fantastic. Elegantly simple menu of course but the steak was cooked to perfection and really tasty sides, green salad and the creamed spinach both great Table service was friendly, efficient and attentive without being pushy and the price was reasonable

Delicious and simple. The ice cream was a nice surprise too

great service, the staff so nice and helpful, food so delicious!

Had a wonderful experience at Flat Iron. The service did not disappoint. We were seated quickly and had our food within 10 minutes. Our steaks were cooked to perfection and dripping with flavour. And that Mac and cheese… to die for. The atmosphere was great and the drinks were yummy! Our server Kelly was also lovely.

We hadn't booked a table but were quickly seated by a nice man. Fast service and good food. This is a popular place which is easy to understand.

Yesterday was my first time at Flat Iron and I was pleasantly impressed by the kindness of Christian who served me and meticulously explained all the dishes. I ate really well and thanks to his suggestions he made me choose some really delicious dishes. At the end I was offered a fantastic vanilla ice cream! I will definitely come back to this place and I hope they give an award to this guy because he made my first visit unforgettable.

I really love flat iron! No matter which location you go to, you're going to get a really good steak at a fair price. It's a simple menu that is part of the appeal, in my opinion. I'd rather have fewer items available and all of them be made perfectly each time. The garlic mash is absolutely fabulous! And while I personally love the creamed spinach, they had a special of kale and Parmesan salad, which was incredible.

Really good value for money. Well cooked and delicious steak. My friend had a burger and that also looked and smelled great. Bonus with the complimentary ice cream to take away even though it was -2c outside! Nice service, would go again.

Very good communication via email about an amendment to our booking, very friendly staff and very tasty food, highly recommend the mash 👌

Good service, food is good but not exceptional. Prices are better than most pubs, steak £14.00, not the best, add chips £4. Suggest the steak bavette instead of the flat iron steak.The mash is very rich = bone marrow. Aubergine is good, also a bit on the rich side, u can order as a mains. U do get a free ice cream cone on departure. Beer is expensive, house fizz is good value. Nearly omitted to mention, free popcorn. All in all way better value than a Fullers or Youngs pub.

Efficient menu and impeccable services

Dimi was amazing and suggested the Picanha steak tonight. The Malbec was also a fantastic suggestion! I will dream about the steaks and creamed spinach

Local 5 minutes from king cross station. It is advisable to book because it is often full. Ordered a hamburger with gherkin cheese and truffle cream (excellent) plus meat accompanied with fries. As a further side dish we wanted to try the spinach with cheese and the puree with fried garlic on top... delicious! Very kind staff and wooden room with soft lights. In 4 110 pounds. Must try!!!!

Tasty and well-marinated steak, quick serving and great side dishes!

Great tasting steak. Managed to walk in and get a table, although it was busy and we were lucky, so I'd advise booking in advance.

If you want to eat steak, it is highly recommended, but there will be a 12.5% ​​service charge.

The food at Flat Iron was outstanding perfectly cooked and flavorful. The customer service was incredible, especially from one of the girls who served us. I didn’t catch her name, but her kindness and attentiveness made the experience unforgettable. Highly recommend!

Booked in today for lunch, lovely looking place from the outside, set on Caledonian road just before it turns into kings cross and gets really busy and affluent. We were greeted by a friendly man who showed us to our table and brought us some complimentary popcorn, and a big jug of water for the table. It was a really nice start and made us feel welcome and relaxed. Inside was bustling with people and had a really warm and relaxed atmosphere and felt so cosy on a wet and chilly London afternoon. Another young man took our order and again was really friendly and our drinks arrived shortly after, We ordered two rose lemonades and an apple and rhubarb soft drink, all were delicious and moreish. Food arrived later and all looked the part, I asked the lady who served the food for another rhubarb and apple drink but was told a bit coldly to find a waiter to take the order and then walked off. Didn't like that exchange and felt quite rude to be honest. Garlic mash was delicious. Thick, rich, buttery, topped with a strong garlic oil and crunchy croutons. Chips were crispy and fluffy inside, seasoned well and could taste the beef dripping. Creamed spinach was deep and earthy and packed with spinach flavour with just a touch of creaminess. Side dishes were fairly small but the flavour they packed was immense. My Mother ordered the aubergine dish as a main as she's a vegetarian, she said it was delicious and being served in a pan was a quirky touch. We ordered three flat iron steaks, two medium rare and one medium. The medium was well done, one of the medium rares was medium well, and the final medium rare was literally half medium, half rare. Cooked really unevenly. We gave them the benefit of the doubt as I expected the beef to still be delicious and tender regardless of the cooking, but we were wrong. All three were so tough and chewy and even a bit watery to taste. There was no real sear to any of the steaks and it lacked any real flavour apart from the salt flakes on top. They literally looked boiled, tasted like it too. The rare half of the unevenly cooked steak that belonged to my brother was literally inedible as it had long streaks of uncooked fat running through it and he gave up and left it on the plate. I desperately wanted the steak to be amazing as everything up until then was so wonderful and wanted this to be our go to restaurant for going out as a family. I hate criticising, and it brings me no joy, and I'm really sorry, but the steak was so unbelievably poor, quite possibly the worst I've ever had and I'm not trying to come across as dramatic, they really had nothing going for them. I've had better from Harvester restaurants and even the local wetherspoons which is such a damning thing to say about a steak restaurant. My late grandmother, god rest her soul, used to cook the hell out of her steaks and we had no choice but to eat them, even they were better. I wish you all the best and maybe today we were just very unlucky or the chef was having an off day, but unfortunately we won't return to find out. Have a wonderful new year and all the best to you all. Christopher.

Delicious steak and chips, great service too!

Had the wagu sirloin, and at £26 was 90% fat and gristle , some of it could not even be chewed and had to be spat out. Worst steak at that price point ever. Fries and mac and cheese were good, service from waitress good, the cut of meat was extremely poor quality and should not have been served. Even more bizarre was the complimentary ice cream cone available to redeem only on your way out the door in freezing December weather- would be interesting to know why they thought that was a good offer?

Great food at a very reasonable price, much needed in today's economy! Feels like the restaurant has your interests at heart in this regard, particularly offering free ice cream and popcorn. I've tried the flat iron steak and the wagyu and both were great, as are the accompanying sauces. Chips are cooked just right and all of the sides are strong. Only small thing is that we were seated next to the kitchen door so there were lots of staff loitering around our table and kitchen noise, but overall this didn't take away from the experience.

We had a table booked for 12pm, not realising that’s when the restaurant opened. We arrived early at 11:45am hoping to just have a drink and wait for our table to be ready. We walked in as the door was open and were told to leave as they weren’t opening until 12pm. Didn’t ask if we’d reserved or anything, just “We’re not open for another 15 minutes”. We cancelled the booking as soon as we left. In the future, keep the door locked until you open if letting customers in the building 15 minutes early is such an issue.

This is a special review for our tonight waitress Fabiana @ King cross Flat Iron. We had a wonderful time and she is one of a kind who took good care of us. Perfect service. Thanks again for your kindness! Till next time FI 🔥

Burger is absolutely tasteless, soggy and way too much onions. Burger had pretty much fallen apart within a minute of eating it. Steaks from here are definitely better.

Oh Barbara 🥹 She was our waitress and she done such an amazing job, we will definitely be back just because of her!
