The locally made tofu is some of the best you'll taste in China. It's soft and delicate, and served in a variety of ways: with fish, vegies and such. If you can't decide, take your pick from the picture menu on the wall. It's located off Guotu Jie, the street parallel to the main drag where the Quanshan New Holiday Inn hotel is.
If you get lost, ask locals for directions; it's a famous restaurant.
