Even burger fascists have flipped for this hip new burger joint in the middle of Sanlitun. Although Hong Kong-run, Let’s Burger has the military efficiency of a New York diner and a 1950s black-and-white linoleum feel. When you arrive you will be provided with a pencil and an order form where you tick off what you want and pay in advance. It seems that the gourmet burger concept has finally arrived in Mainland China. Their offerings run the gamut from the traditional cheeseburger to Wagyu beef burgers with caviar and foie gras. Whatever you choose, the patties are cooked to perfection and the toasted buns, a key element in any good burger, rival those in the Red States. The side orders of chunky French fries and spicy onion rings are also a safe bet. There is also a large condiment counter where you can serve yourself five different sauces for your burger.
