Walk toward south from the east gate of Lama Temple for about 20 meters and go across the street. The restaurant looks a bit like a pagoda with wooden frame and dark yellowish sign of some characters like “Beijing Guotie Miantiao (北京,锅贴,面条)”

Big crowd (there were at least a dozen of us), very tasty food and a great little restaurant. The bill came to 18RMB per person (no joke).
