Honest Burgers Brewer St is a branch in Soho, London, on Brewer Street that serves handmade burgers. It offers the Honest Burger and smashed burgers with rosemary fries and chipotle mayo sauce, and the soft buns and sauce define the flavor. Beef patties, onion rings, and buffalo wings are available, and coleslaw can be swapped in as a side. More seating is upstairs and the toilet is on the second floor, and wait times before and after ordering can run long.
