LA-style smash burgers (made with extra-thin, crispy-edged patties) have become super fashionable in London in recent years. But if you want to try some of the best of their kind, head to Bun & Sum. Winners of the National Burger Awards 2024, Bun & Sum started slinging burgers and sides in Bow before expanding with sites in Hackney and Camden. At any of the locations, expect to find classics like the Big S’Mac (with two patties, American Cheese, lettuce, pickles & house S’Mac sauce), the Motz (with sliced onions smashed into the patties) and the Green Chilli Cheeseburger (with two patties, American cheese, fresh jalapeño, onion & house Fire Sauce) – and a lengthy queue.
