I strongly recommend Yangshuangchang in the south section of Huangshan Road. I like to eat pure mutton and whip soup. Recently, the mutton soup in Zhangdi, at the entrance of whip treasure park, which costs 2 yuan once every two days is also ok, but it mainly eats vegetables. If you are not afraid to go far, the mutton soup next to Fancheng Mosque is also very good.
