Both the first floor and the second floor are cheaper (1- 10 yuan), and the food on the second floor is a little lower than that on the first floor, with little difference in taste. The prices of the two flavor canteens are more expensive than those on the first and second floors (above 5 yuan), but they also taste better, especially underground. They won't close the door halfway until around 9 pm. If you miss the meal time, you can go there to eat, and there are various flavors for you to choose from.
