2. Zhangye Road Snack Street. It's at Zhangye Road Pedestrian Street, Yongchang Road (also at the entrance of the ancestral temple). Main products: roast mutton, vegetarian cold noodles, local candy.
3. Near Lanzhou Cigarette Factory, behind the building of Huangcheng Mom Hot Pot, there are also Muslim snacks (saying that Muslim snacks in Lanzhou are really popular. . . )
The cold noodles and barbecue at the east entrance of the square are also great, but I don't know what the road is called. . . .
