Byron in Lambeth

I came with my mum on my birthday to celebrate and we had the most delicious food, service was incredible and Florin went out of his way to ensure I was celebrated. Incredible team and always top standard food, especially the ice cream.

The staff is always nice and welcoming! Special thanks to Florin my waiter.

Like other reviews, the servers were very friendly. So much so that I feel pride in my job! For Koreans, I recommend cooking at medium-well done or higher! I was satisfied with the cost-effectiveness, atmosphere, and taste! The free ice cream looks ordinary, but it's a taste I've never had before. Be sure to try it!

5/5 as always. My server was flavi 🤲🏼

Has to be a little overrated as a chain now. Once was good value and new now nothing special.

I've just had a super streak!! Dan was super helpful and thanks to his advice and professionalism I had a great time! Totally recommended!!

Always love going to the Flat Iron steak restaurant chain, such great value for money compared to other places, the steaks and side orders are so tasty. Warm friendly staff too, love the little meat cleaver you get at the end to receive a free yummy ice cream.

A great venue. Staff were awesome, especially our waiter. (apologies, but I have forgotten her name, but she works in Biology!) Got our order and the food arrived within 15 mins. The steak was great along with the truffle mac and cheese and the fries. The plate (the food came on a wooden board) was duely demolished. As we were leaving you get a ice cream which is a great way to finish the meal off. All this at prices you would struggle to get anywhere else. Hats off to the Flat Iron!

Nice location, the food was amazing and so was the drinks, the server Victoria was really nice also!

Crazy good steak, delicious side dishes and good value for your money. Definitely recommend this place for anyone looking for perfectly juicy and tender steak. Service was great and welcoming. Huge thanks to our server, Victoria, for the warm welcome and swift service.

best steak and drinks ever trust me

A great value, but incredibly tasty steak and sides, with attentive servers, and lovely little free extras like popcorn and delicious ice cream. Would definitely take my meat eater friends there

Florin and staff are so lovely! Thank you so much for taking of us! We will be back

Great Food, even better service. Lex (waiter) was great

I loved everything. Good quality of food, great price 👌, very kind staff and amazing atmosphere 😀. I can still feel the juice steak in my mouth. The wine was so good also. I will def go again and again. I fully recommend it.

This was a fantastic place to eat! - the food & service was brilliant! 👏 We went for my husbands birthday and they made the whiole thing really special including putting together a pudding with a candle and singing Happy Birthday! I would definately reccommend - the mac and cheese is to die for!!! ❤ Thank you to the team. We will be back!

Famous restaurant chain only for steak. Wonderful service, simple menu, with only one item to choose from. The steak wad cooked to perfection.

Eat there today with our two young boys, they have loved it! The food, service and Ice cream!

Great restaurant with great vibe. Staff is really fast and very friendly. Food was done perfectly

Wow! Just wow! Everything about this place is amazing! The flat iron steak (with peppercorn sauce) was perfectly cooked and tasted outstanding. The side salad and the creamed spinach were so good too. Service was 100%, and the ice cream at the end was the cherry on the top of an outstanding experience. The mini cleaver as a knife was fun too.

Nelle looked after us like an absolute wizard, made Harry Potter look like an amateur.

Food was really nice, such a great price, Nella our server was lovely - will be back !

Nella was the best host. Kind, friendly, knew everything on the menu. And it was her first day, how good will she be in a week month year. She’ll probably run the place.

Great food and service by Florian!

Niko Niko Niko what an amazing waiter, great personality, we stumbled on this flat iron by accident and what a great accident it was! Food was amazing i left feeling very content. Service was above and beyond and out of this world. Definitely be back even if it is just to see Niko. Thank you so much for your understanding and patience and excellent recommendations 😊

Great food, excellent value and superb service from Florin, thank you!

the best truffle burger i’ve ever had, truly amazing!

Quick and friendly service, delicious food. The complimentary ice cream at the end was the cherry on top to a great dinner!

Affordable and tasty meat option in London 😋. Excellent customer service. Very decent portion sizes too 👌🏾

The best restaurant!!!! And Nikol is the best And lovely waitress ever😍😍😍😍

Nikol is really our favourite waitress, very nice and easy to chat with~ It‘s a pleasure to meet you!!! I’ve always wanted to come to this restaurant before. The food is very delicious😍Whether it‘s steak or sides, tastes very good! We ordered steak, fries and salad.

Incredible food, they gave us extra pop corn too (yes they have pop corn instead of a bread basket) and it has more than reasonable prices. Would recommend to anybody!

Excellent service and food thanks Talia

Roberto was an amazing server. We had a laugh with us and was just brilliant with service

Absolutely brilliant, will be back soon. Great staff too. Thank you

We had an amazing experience at Flat Iron, thanks to Mohammed M. His service was absolutely 10/10, super attentive, knowledgeable, and genuinely enthusiastic. He went above and beyond to upsell in the best way possible, guiding us through the menu and recommending the perfect cuts and sides. Every suggestion he made was spot-on, and his hospitality made the entire meal even more enjoyable. If you’re dining here, ask for Mohammed! He knows his stuff!

Had the pleasure of being served by Mohammed M - his service was absolutely impeccable, great attention to detail and gave us an excellent recommendation for the bavette wagyu steak which was extremely delicious. 10/10!!!

Best mashed potatoes I’ve ever tasted

Such a cute restaurant and such good vibes! Our server Florin was lovely and took care of us!

We had a splendid time here, our waiter Roberto was exceptional and made the experience amazing. After Roberto left however we were soon ushered out of the restaurant by a different waiter even though we had only been at our table for 45 minutes. We felt very rushed and pressured to leave by him. Grrrrrrr

Everything was wonderful, especially Nicol's attention, she tried very hard to speak Spanish with us and was very friendly, she should be promoted! Hahaha, very grateful to her and in general to the entire place. They made our dinner very pleasant

Great experience at The Carcass Club in Flat Iron Waterloo! The food was excellent — perfectly cooked and packed with flavor but the real highlight was the service. Our waiter, Christopher, was an absolute star! His warmth, and attention to detail made the evening even more special. We can’t wait to see him again at Southbank!

Pre theatre dinner. Lovely Steak. Great service - especially from Roberto.

I love this place, small intimate and really well run. Basic menu which my girlfriend loved, food was out super quick, perfect meal before the theatre! Free ice cream on the way out is a nice touch! 😋

Roberto was a perfect host! Nice service!

Initial service was mediocre, the meat was traditionally good, and Lucas was great. Thank you Lucas!

Not as friendly as the flat iron in Westfield but still lovely food

Great steak, amazing kale salad, mashed potatoes, and macaroni & cheese. Reasonably priced and great service. You can't go wrong here!

Decide to dine here after a friends recommendation and we had such a great meal! The steak was cooked perfectly, the sides were delicious, and the popcorn was a fun little touch. The whole place has a really nice, relaxed vibe too. Tom was our server, who looked after us so well. He was super friendly, really knew his stuff. You could tell he actually cares about making sure people have a great time. Definitely coming back!

Great steak and service, thanks Roberto! :)

Had a lovely lunch here over the weekend. Haven’t been to a flat iron before but i was thoroughly impressed by the quality of the food and service. Tom made sure everything was seamless and his recommendation on the Mash & Spinach was spot on. It’s not often i focus on the sides in a restaurant like this but these were great (as was the whole meal). Would recommend stopping by if you’re in the area

Great steak and loved the spinach and truffle mash. Tom was great and even gave us some recommendations for upcoming London gigs which made our weekend.

Came here with my partner for our anniversary dinner. Tom’s service was excellent. His recommendations for food and drinks were spot on, and for someone like me who can eat a lot I was very grateful for this. All in all great service and food and their ice cream is amazing!

Really nice food and atmosphere!

Came to check out why the queue is always so long outside the Flat Irons and was not disappointed! Food was 🤌Service was exceptional- Tom is very attentive and personable. Would definitely visit again

Food and atmosphere was great! I had the burger which was really goo, and I’ve had a lot of burgers! Our server, Roberto was very attentive and hard working! Really great overall!

Roberto was amazing, highly recommended was amazing.

Great service, food comes fast and waiters are always on hand to help. A special thank you to Talia and Lucas.

In this particular branch of Flat Iron there was zero waiting time and I haven’t been to a restaurant this year and had such memorable service. We ordered 5 steaks (medium) with the creamy spinach which were excellent. Much appreciated is the service from Talia and Lucas 🤩 I’ll be back again!

The steak is yum and I LOVE the mushroom sauce. The mash is very creamy. And Roberto is super friendly and helpful!

excellent steak and fries, we enjoyed very much and would come back again! the burger was not bad too, for those who dislike pickles i would request to take them out. service was great too and the free ice cream when leaving is very nice of them and delicious!

Had a great experience at Flat Iron! The steak was delicious — tender, juicy, and cooked perfectly. Great value for the quality. Special thanks to our server Florin, who was incredibly friendly, attentive, and made the whole dining experience even better. Will definitely come back!

This is a fantastic place. The food (steaks) is delicious, juicy and tender. We ordered a green salad and it was surprisingly good too. The service was excellent. Many thanks to Mr. Lukasz, who navigated us and secured us a table after a reasonable eating time. The idea of homemade ice cream as the “one for the road” dessert is fabulous!!! Thank you very much. We hope to visit you soon.

I have been to flat iron on numerous occasions and always been impressed with EVERYTHING ! Shoutout to Lucas!

Florin was a great server! The Ribeye Steak was so good! Loved it! Highly recommend the chips kale Caesar (if available because it was a special). 100% would come back!

Florin was so nice to me, appreciated your kindness!!

Carcass club was amazing, The ex dairy estate ribeye was delicious. Shout out to Koko for the attentive service

Wonderful meal at flat iron, easily the best chips in London. Fantastic service from Roberto - so charismatic, informative and friendly. Great service.

Had a lovely evening at flat iron Waterloo with my sister, I enjoyed the Waugh steak and she had the triple cheeseburger. We were served by florin, he was very attentive and polite.

Incredibly simple concept yet so effective. The food menu has a few mains (mainly the steak) and many sides. Everything is really delicious, special mention for the Mac&cheese, Spinach and the flat iron. The cocktails are pretty good too! The atmosphere is really busy and lively, in a nice way, and the service is incredibly efficient and fast. We have received the food within 10 mins of ordering and special mention to Nico, his vibe is really great and we really appeeciated his service. Will be back!

Had an amazing dinner here pre-theatre before heading to the Old Vic, great food and atmosphere and Roberto was a brilliant server

Flat Iron is strange in that I'd ecommend it for everything - but the steak is in the passenger seat for the evening. One of the only downsides was the popcorn to eat as a starter. It was welcome to snack on but felt a bit more like a gimmick than anything else. We had the wagyu strip for the evening and it was pretty decent, but not near as good as what you'd get in a dedicated steak restaurant. What I was mega impressed with was the sides, service, and soft serve to finish! We tried the: chips, creamed spinach, mash, and truffle mac - the latter two being so good we ordered more! Service was top notch, with check-backs and our top man Luigi being so kind as to knock some drinks off our bill as an act of kindness. The ice cream to finish was also delicious and kept Flat Iron in my mind for the next time I fancied a laid back dinner with mates. For the cost as well, it is extremely reasonable for a mates night out and would highly recommend for a mid-month dinner out. Will be returning!

The atmosphere was really good, the food is really very good and thx Roberto for the great service;)

Very beautiful venue, awesome staff member koko, with his great work ethic and high energy he really made our second visit amazing, we will be back! GET THE MASH! It's so good!

Very good Iron Steak for a nice price (£15)

As always the food is amazing! Koko was our waiter today and he was awesome, knew all the answers to our questions and definitely made our experience 10times better!!! The venue is beautiful as well good for some pictures! 🥰 will be back soon

Had a nice birthday meal in this branch - Koko and the rest of the team were outstanding. Meal was great and so were the drinks - Thank you guys

Good food and good location! Lovely food and great service - the staff were genuinely polite, respectful and courteous while also having good energy; a 5 star customer service experience for sure! Special thank you to Joseph for making us feel comfortable! Would definitely recommend! Thank you! Thank you! Thank you!

Everything was amazing, especially the service from Koko and Amelia. #Koko the best

Chris made the meat taste better with his awesome service and smile. We will return!

Chris was Amazing food was great

Koko attended to me 2 days ago, and made sure I had everything I needed, would definitely recommend

Had the best meal at Flat Iron Waterloo. Our server Chris was so friendly and attentive, he really made the whole thing a special experience. Thank you!

Florin was our server and he was amazing! I have a food allergy and he guided me and helped make sure my meal was safe to eat. Food was SO GOOD. Great vibes and they made my boyfriends bday so special with ice cream and a candle!

The usual good experience from a flat iron restaurant. This one is spacious with plenty of seating and is in a very nice location. Definitely worth a visit for its side dishes and the steak is mostly tender and of good quality. Instead of a Scottish bavette, this restaurant has the option of sirloin instead.

I celebrated my bday there, roberto took great care of us and it was a quick, amazing dinner and friendly service, the steaks are delicious as always, the ice cream is the perfect way to end a wonderful meal and a lot of warmth from the staff

Phenomenal service from the wonderful waiter Roberto! I dined here for my boyfriend’s birthday and from start to finish, we were taken well care of. He really helped make my boyfriend’s day even more special! Also the speed of service was amazing. Thank you Roberto and the rest of the flat iron team :)

Alice was amazing! She served me and my friend and was super pleased with her service. She was so friendly and helpful when needed. Would recommend 100% and would definitely return to this branch specifically.

The service is very warm, the dining experience is great, and you can get free ice cream before leaving! ! very delicious

The steak and burger were spectacular… I would always come back!

We were served by Magic Mike, who gave us great service and made us feel very welcome. Thanks for the jokes. Food was good too. Emma & Charlotte

Thumbs up for atmosphaire, cosyness, fantastic personel, on time everything, crystal clear & short menu , nice prices but then its the serious question like.. " what does the food looks like?". Well long story short its one of those places where kid is just satisfied only with the free ice cream at the end. So ,ya.. not the place for 11 year olds.

AMAZING AMAZING AMAZING, at this point I’m a H*e for flat iron! IM IN LOVE😍. Florin was amazinggggg thank youuuuu!

I went to the Tottenham branch and went there too. You might not be able to understand the server’s pronunciation, but ㄱㅊ… As expected, it was delicious. I chose mushroom sauce and chili mayo sauce, but I personally think chili mayo tastes better (it balances out the flavor).

We visited on 8/3/25 and what a visit! My husband and I had visited before another location but Saturday was the day to take our 7 year old son! Now the food was amazing service speedy! However what made it really special was Chris! He was kind, friendly, attentive and chatty- but the good kind of chatty! Chris truly went above and beyond to make Freddies dirt experience nothing but 11/10! A bag of popcorn to go and spare ice cream token which he has shown to absolutely anyone who he can! Thank you so much Chris there’s doing your job and then there’s DOING your job!

I had an amazing experience at Flat Iron! Our server Koko was absolutely fantastic—attentive, friendly, and made sure we had everything we needed. The service was quick, and the food was delicious. It’s rare to find such a perfect combination of great hospitality and quality dining. Highly recommend this place!

Shoutout to Roberto!! Great service! His recommendations were the best!! They serve very fast and the food is 20 Out of 10.

Fantastic experience with the family at the Flat Iron restaurant. The meat was excellent, served perfectly cooked and very quickly. We want to thank Roberto for the wonderful welcome and the warmth he showed towards the children. We can't wait to return.

I've got the pleasure of being served by Koko and Nico. It was a wonderful experience the food was delivered incredibly fast and it tested amazing. Our waiters were super attentive and I would definitely come back :)

The service was or is the best and fastest service I have ever received in the best way possible. Food was really good ans drinks were nice.
