Pasta: 4.5-6
Casserole: 6-9
Maocai helped himself, vegetarian food 6, 7 yuan a catty.
Second floor, including Sansi Restaurant: Generally, all the windows are made by private contractors, about 10.
The rice in the third restaurant is slightly more expensive than the vegetables on the first floor. You can add rice. The quality of rice is better.
There are all kinds of cooking windows in private restaurants and an old Chengdu Sichuan restaurant, which tastes good.
On the third floor, there is HKUST's reception restaurant (which can be used for general parties and class parties) and private restaurant (which I personally think is quite affordable).
Backstreet: Now businesses are opening their doors one after another, but the environment is not very good, but you can find food if you like.
Some shops don't look good, but the taste is ok, such as Jiangxi restaurant.
I hope it helps you!
