It's too simple. If you want to eat mutton, go to Ma Laoliu on Tongwei Road (the eastern end of Zhangye Road Pedestrian Street), go to Gannu or Ma Zhonghua (there are many branches in Lanzhou, please tell the driver if you want to take a taxi), go to Yinfeng (Xiaoxihu or Beibinhe Road) if you want to eat stir-fry, eat hot pot if you want to eat Xiguan Cross, and eat fat beef at Hongding or Binhe Road.
