2 canteen food is the best, followed by 1 canteen, and 3 canteen is the worst.
In addition, there is a Lihu restaurant. The food is good and formal, but it's more expensive.
In the second canteen, you can eat enough for 5 yuan, and there is probably a piece of meat. 10 yuan can eat quite well.
In the third canteen, you can eat all kinds of bugs for 5 yuan. 10 yuan can still eat all kinds of bugs.
Lihu restaurant is basically rice and noodles. Usually seven dollars, a dish covered with rice, and meat, a lot. I am a boy of 80 kg, I can eat!
