The most famous one should be Baifu Group. Baifu Bakers are found everywhere in Urumqi, just like KFC.
There is Huoyanshan Group, below which there are Huoyanshan Hot Pot, Xiaoguzi Restaurant Chain, and the first set and three different restaurant chains in Xinjiang.
Basically, these two companies are the best. I hope I can help you.
Of course, there are KFC and Dicos in Urumqi, which are found all over the country, so I won't mention them one by one.
However, there is no McDonald's in Xinjiang.
