You’ll often find a queue snaking out the door of Chequers, a popular weekday sandwich spot in Covent Garden. It’s a slightly chaotic grab and go situation, where you squeeze into their cupboard-like shop to make your order—it’s all written on huge boards behind the till. Choose from focaccia or baguettes, and fillings like tuna mayo or chicken escalope, then wait outside until they usher you from the crowd of people waiting for their sandwiches, back in with hand signals through the window. You get a free soup with every sandwich for under a tenner, making it a great-value lunch deal for the area.
