Not much to look at and a bit hard to find, but this place has some amazing Xinjiang food for super cheap prices. The hand-pulled noodles are the best I've ever had. Wash it all down with some Xinjiang beer. A great place to take visitors as well for a more real glimpse of China than be seen in some of the fancy places in Sanlitun but with the assurance that the food should be agreeable to most Western tastes.
