The Flat Iron Philosophy: Exceptional Steak for Everyone
Since opening its first permanent doors on Beak Street in Soho in 2012, Flat Iron has rewritten the rules of British steakhouse dining. By avoiding expensive prime cuts like fillet and ribeye as their core offering and instead mastering the flat iron cut—extracted carefully from the shoulder blade—Flat Iron delivers top-tier marbling and flavour at a fraction of high-end steakhouse prices.
The Star of the Show: The £14 Flat Iron Steak
The centerpiece of every table is The Flat Iron Steak (£14.00, 520 kcal). Cut to approximately 200g from native British breed cattle, the steak is seasoned with crunchy Maldon sea salt flakes and flash-seared on high-heat planchas to medium-rare. Sliced into succulent strips and served on an oak butcher board with a complimentary house green salad, it is remarkably tender and flavour-packed.
House Sauces & Legendary Beef Dripping Sides
To accompany your steak, Flat Iron makes four house sauces daily for just £1.50 each: a velvety Homemade Béarnaise (£1.50, 180 kcal), cracked Peppercorn Sauce (£1.50, 140 kcal), fiery Smoked Chilli Mayo (£1.50, 160 kcal), and zesty Fresh Herb Chimichurri (£1.50, 120 kcal). The essential side dish is the Homemade Beef Dripping Chips (£4.50, 420 kcal), made from British Maris Piper potatoes fried twice in rich beef fat for unrivalled crunch.
Complimentary Popcorn & The Legendary Free Soft Serve
Hospitality at Flat Iron begins the moment you sit down: servers deliver a vintage enamel mug of warm beef-dripping spiced popcorn free of charge. Filtered still and sparkling carafes of water are completely free and constantly replenished. When you pay your bill, you are handed a tiny stamped metal cleaver token. Hand this to the ice cream master at the exit counter to receive a complimentary freshly swirled cup or cone of Tahitian Vanilla Soft Serve (£0.00, 180 kcal), topped with chocolate grated from a solid block of dark Venezuelan chocolate.
For food lovers across the country, the Flat Iron Menu represents a premier destination for satisfying cravings and enjoying premium flavors.
