There are almost seven canteens in Siyuan. The bigger ones are Hongyan and Fuyuan, but these two restaurants have a general environment and are very popular. In the middle are the snack cities Kaifeng and Cadbury, which have the best environment. The rest are Muslim restaurants and sunshine gardens.
Basically, the rice tastes the same, a bit like a Muslim restaurant. There is a kind of meatball hot soup that is not bad. I hope you can find your own food.
