Flat Iron Kings Cross is a focused steak restaurant at 47-51 Caledonian Road, a short walk from Kings Cross station. The straightforward dining room follows the group’s original aim of making carefully sourced, well cooked beef accessible in an informal setting, keeping the experience centred on a concise food and drinks list.

The signature flat iron steak showcases a tender cut taken from the shoulder and prepared with close attention to butchery and grilling. Changing blackboard specials add variety through different breeds and cuts, with a Wagyu steak of the day giving diners the opportunity to explore richer marbling alongside the dependable house favourite.

Beef dripping chips, crisp bone marrow garlic mash, creamed spinach, green salad, truffled macaroni cheese and roast aubergine complete the plate. Béarnaise, peppercorn, wild mushroom and smoked chilli sauces let each customer adjust the richness and seasoning without distracting from the character of the meat.

A compact wine selection is designed around steak, while beer and cocktails include classic and alcohol free choices. The short menu makes ordering simple but still supports a full meal, moving from the restaurant’s customary opening snack through beef and sides to a sweet finish after the main course.

Address: 47-51 Caledonian Road, Kings Cross, London N1 9BU, United Kingdom
