The cheapest and most affordable ones should be Han Ji Coarse Grains Pavilion and Guest House.
Han Ji Coarse Grains Hall: Turn right on the street from the south gate to Qingquan Village and go straight to the innermost part (that is, the courtyard of Friendship Internet Cafe). Really affordable, it is the first choice. And whenever you go, no matter how many people, no matter how many dishes you want, the boss will give you a dish. Last time I went to our dormitory, I would give us a tomato mixed with sugar. It was a big dish. If you are a girl, you can't get it.
Yingbin Restaurant: On the street from the south gate to Qingquanzhai, the food is also quite affordable, and the plates are as big as they are. I don't like its environment (personally), but the food is delicious.
Then there are Chongqing Roasted Chicken and Northeast Chinese Restaurant.
Chongqing Roasted Chicken: Located in Qingquanzhai Street, opposite the Northeast Restaurant. People in our dormitory have eaten there many times, and I don't like it very much (I don't know why I just don't like it) The food is good, but it's more expensive, but it's still a good place to eat.
Northeast restaurant: it can accommodate up to 80 people. The food is a little cheaper than Chongqing roast chicken, and it is quite distinctive.
Then there is the expensive casserole: walk along Qingquanzhai Road to the seaside, cross that road, and it's on the right hand side (sorry, I don't know the difference between east, west, north and south). It's too expensive, and the content inside completely adheres to the principle of expensive! Its main reason is that the environment is good, the special dishes are well cooked, and the rest are just like that. If eight girls can't spend 300 yuan, they can eat well around 250 yuan.
Lao Xiong: It's also on the street where the casserole is too expensive, but on the left, he is a Sichuan restaurant, and the food is very spicy. I don't eat any spicy food, so ... but the grade can't be too low
Zizhulin: It's a place that costs money and can't eat well. The food is too small, just a Fluttershy, alas! I have been there once and will never go again.
There is also a hot pot restaurant-Chuanmeiyuan: it's not easy to find. It's a buffet in Qingquanzhai. Per person 16 yuan, and the base material is calculated separately. Going to the dormitory for dinner is about 180.
