I know roast leg of lamb is very delicious. Take Xuanhua Street and turn to Li Xuan Street at the intersection of Zhong Xuan Street and Xuanhua Street. If you don't choose, you will see a shepherd roast leg of lamb, which is in the basement. His leg of lamb is roasted and eaten, which is very delicious. Beijing roasted large intestine, fried meatballs and beef soup are all delicious. I stayed there for a long time. Go and have a look. . . good luck
