This restaurant specialises in instant-boiled mutton, a traditional Beijingese charcoal hot pot dish. Prized for its fine lean meat without the gamey taste, lamb from the Mongolian Sunite prairie is used, along with beef from western Shandong. Specify how fatty or lean you want your lamb. The bite-size shaobing flatbread goes well with the hot pot. Round off your meal with sweet shaobing covered in sesame sugar.
