Like its older sibling, the new branch of Flat Iron – a ten-minute wiggle away on foot through Soho – follows the same one-dish policy. The signature flat iron steak (as top blade is known over the pond) is served perfectly pink, and reasonably priced at just a tenner. It’s easy to ramp up your food bill though, once you’ve said yes to dripping-cooked chips (£2.50), a sauce (£1 each) and greens (£2.50). But the béarnaise was silky smooth, Fred’s sauce had a mild kick, and the leafy broad bean top salad had a delightful peppery crunch.

Beyond the namesake steak a handful of daily specials are explained by the eager-to-please staff. On our visit, the wagyu chuck steak (£15) was disappointingly chewy, and the burger (£15) – also made with pricey wagyu beef – scored high on flavour but low on engineering, with meaty crumbs of the patty falling apart after just a few bites.  
The stripped-back look, with bare brick, antique-styled panelling and age-of-steam décor certainly looks the part in the airy dining space at the rear, though the acoustics suffer; lip-reading will come in handy if there are more than a dozen diners.

As for the mini ‘flat iron’ meat cleavers – they’re quirky but gimmicky, since the steaks come ready sliced. Oh, and they’re not to be snaffled as ‘souvenirs’, as the menu politely points out. Consider yourself warned.

For a steak lover, Flatiron has a winning concept: do away with fancy frippery and serve a decent steak for a tenner. It's queuing all the way here, so choose your time wisely. At 12.30 on a rainy Saturday we walked straight in. The restaurant goes for the distressed warehouse vibe - wooden seating, metal hooks, etc. It works well, and little cleavers you get with your steak add to the experience. These are adorable and a nice touch, and whilst the menu warns you off sneaking yours away for a souvenir, you can buy one for £10 if they take your fancy. It's busy and bustling inside, but we received surprisingly personal service from our waiter, who sat down and explained everything to us. We both opted for steak, chips and a side salad - simple, but effective. The steak was tasty, particularly for the price. It wasn't the most tender or memorable steak, but it was moreish and overall pretty good quality. The same goes for the wine. The rest of the meal delivered too -tasty chips and salad, rounded off with an excellent ice cream sundae to share for under £4. We left full, happy and with pockets not too much lighter. It's a great option for those who don't mind a potential queue in exchange for a good value feed.


No words can describe the deliciousness of the steak at flat iron. The menu is pretty simple as there is just one main course: The Flat Iron Steak. You can have it cooked as you want, but medium rare is the one recommended. The steak comes with a small green salad as a side. But there are 6 different options of additional sides to order: Sophie's salad, the fries and the grilled aubergines are three of my favorite.

Expect long queues (in the order of 2 hours). However, the queuing system they have in place is clever. You give your phone number and you receive a text message with a link. The link contains live information about your "reservation" and the number of tables before you. You can check your order and wait for a table while you are having a drink at a nearby pub. Believe me the experience worths every single second of your wait.


Hidden between all the cool guitar and music shops, is a gem of a steak house. Why is it a gem? £10 for a delicious steak, you literally can't get better than that in London! There are no reservations taken here but you leave your name and number and they text you when a table is ready for you. We popped into Alley Cat a few doors down to get a drink whilst we waited. I only had to wait 10 minutes before I got the text and had to down my drink! It might be worth waiting outside if they tell you it's only going to be a 15 minute wait. We were taken to our table where a mug of popcorn and a full jug of water was waiting for us. Our waitress then proceeded to tell us what steak they were serving today and what the specials were. On the occasion I was there they had a £10 burger or a steak baguette. I ordered the steak of course with a bearnaise sauce, chips and creamy spinach. Absolutely spot on, the steak was tender and just how I like it, medium rare. The chips were addictive, I couldn't stop eating them even though I was full. We made the mistake of ordering two, you really only need 1 portion per 2 people. Even though the steak was amazing, I have to say the creamy spinach wasn't far behind, it was absolutely divine, if you like spinach you have to try this! I went on a Thursday at 6pm, when I left at 8pm the place was still packed but don't let the no reservation thing put you off, it's totally worth the wait!


The five star review 'thing' sometimes worries me. Like, seriously, all these people think it's THAT good? However, in this case, I think Flat Iron deserves the rosette. It's outrageously popular, and you'll usually have to wait. Except last night, arriving at 6pm for a table for two, we didn't have to wait at all. We were ushered through by the most friendly, sweet staff you could imagine and that set a lovely tone for the meal. 

Your options for food here are limited, so if you don't like steak, don't come. The original Flat Iron steak option is a cheeky tenner and it comes with a side salad. We added on creamed spinach and fries to share, washed down with a variety of cocktails. I recommend the Plum Aperol Spritz - absolutely scrumptious. The food was excellent too, in fact it was hard not to compare the experience to Tramshed which does a similar affair (albeit at three times the cost). There's only one dessert on the menu. It's a salted caramel sundae and it works well. 

In short, Flat Iron has its price point right, the customer service spot on, simple straightforward decor and a great menu which delivers despite it being small. Can't wait to go back. 


Where else can you find a steak for 10 pounds, including a salad. Fine you might find it in the staff canteen (for 9.99 actually, with fries but without the salad) but that is no match for the simple looking yet utterly delicious flat iron steaks that are in the eponymous restaurant. In fact, not only is their steak wonderful, they also have a burger that is constantly rated one of the best burgers in London. It is not always on the menu so every time I go there (and it is way too often) I always get it when it is available, and savour it as though they might take it off their special seasonal menu anytime soon (they haven't thankfully!). Craft beers and great cocktails accompany this place which used to have snaking queues but since they have developed a buzzer system where they take your number and call you when your table is ready, this has helped to hide that crowd-detering queues. Well at least you can go shopping nearby while you wait due to its amazing location. 


What a wonderful chain of restaurants. Flat iron provide good quality steak for only £10 (sides and drinks are extra).

Using the less favoured but more flavoured 'flat iron' cut, which comes from the shoulder of the animal, the waiting staff will recommend that you have this cooked medium rare. I certainly wouldn't go any higher than that but would suggest that the more adventurous consider having it rare or even blue.

The sides include dripping cooked chips, wilted spinach, seasonal greens, as well as some daily specials. There are also often daily meat specials too, which can feature the Japanese Wagyu beef or their handmade beef burgers.

The drinks menu is limited but sufficient to cover everyone's needs with wines, beers, cocktails and good soft options.

One consideration, however, is that you can't book. For this particular restaurant I would recommend arriving before 6pm to ensure that you get a table. If you do have to queue they will take your mobile number and contact you when there is a table ready for you, allowing you to visit the local shops, pubs and/or bars.

Good quality food in a nice and quirky setting. 


A fail safe option for good quality steak that doesn't break the bank. I visited Flat Iron for an early lunch, so luckily missed out on the queues. The service was friendly and efficient. You're given an enamel mug full of popcorn to nibble on while you decide what to order - a definite plus. I went for the Flat Iron steak and shared sides of dripping cooked chips and creamed spinach. The steak was great quality and brilliantly cooked. The sides were delicious but incredibly rich! I would suggest sharing one side between two. The creamed spinach was to die for, with a tasty hint of nutmeg. Brilliant value, good service and great decor. Highly recommended. 


Mega amazing and insanely well priced!! Staff were the nicest and just really relaxed too. Food was incredible and can't knock the free popcorn snack followed by free gelato! It's a must but get there early as no reservations can mean a long wait!


This was our second visit to Flat Iron and first dine in experience (we couldn't get the table last night). Flat Iron does the best steak in town for a tenner. The chips are possibly the best I've had in London. It is the perfect pre-theatre dinner. Get there just before 6 to guarantee a table, otherwise be prepared to wait a minimum of an hour. We were prompt;y seated on arrival. The waiter who served us was very attentive even with the crowd building up in the restaurant. I cannot wait to go back already. P.S. Love the cleavers!

A great tasting piece of steak every time and the novelty factor of a mini cleaver for a knife doesn't wear off. Friendly service and eager to please. Free ice cream on the way out. Great experience. I went here with my cousin who had just moved to London from Canada. He agreed it was the best steak to had tried in London so far...


The steak at Flat Iron is always fantastic, the service can be a little more up and down!  Perfect for a pre-theatre bit if you can get there early enough to grab a table, the food is served quickly.  We were seated at the large table at the back of the restaurant, slightly around a corner and I think the phrase 'out of sight, out of mind' sums up the situation perfectly.  It took 20 minutes for our order to be taken (in a restaurant with many option perhaps this is ok but when there is only one?!?), food came quickly but then again when we wanted to get the bill and leave there was no one to be found and we were left with our empty plates in front of us for a while.  However, the food itself makes up for it.  The steak was cooked to perfection, all sides added something whilst not taking away attention from the main event.  Will definitely be back again soon. 

Yes definitely one of the best meat in London! And it's cheap. But you may have to share your table, so it's not the best place for a romantic diner. Be careful the queue can be up to 2 hours !!


Do not come here if you want to be spoilt for choice because it is a guarantee you won't be, but if you love steak as much as I do, Flat Iron will hit the spot! Cooked to perfection, it was one of the juiciest steaks I've had! 
Dripping chips were a real treat too! Everything about the place is unassuming and simple but that is no bad thing.
A perfect example of excelling in a niche.Sometimes getting simple right is difficult but Flat Iron have done just that!

Simple and very tasty must visit for steak and burger lovers. I had the standard Flat Iron steak with peppercorn sauce, a side salad and excellent creamy spinach - a Paleo delight. Great concept with consistently good quality. Wish they'd start serving coffee. 


We thoroughly enjoyed dinner here and will certainly be back! We were prepared for the wait, and grabbed a drink in a bar nearby (they’ll text you when the table’s ready). It was impossible to resist the wagyu beef special, but as it was our first time here we opted for a classic Flat Iron steak too and split half and half. The classic steak was very good, but the wagyu was spectacular. A side of creamed spinach was delightfully moreish but we could have done without the chips. The accompanying Old Fashioned cocktails with blood orange oil were probably the best I’ve had in London, certainly top five.  


I always go to Flat Iron for the burger. Tried the steak once and did not love it so always find out when they have special burgers. The burger here is very simple, a big bun and a big patty and what makes the burger is the sauce, usually Bernaise with a truffle or a similar twist. One of the better burgers in Londontown.

Went here for dinner on my birthday, despite the large queues we got seated within 5 minutes. The met was well cooked medium rare as per their recommendation and the chips were fantastic. Good value wine list and a couple of decent cocktails too. Nice simple menu enough to satiate your steak fix without the added expense that a visit to Hawksmoor/Goodman requires.
