I only went here once but the food was excellent and it was nice to eat a vegan local-style meal with the locals! When I was there the guy had invited 4 friends and I was the only tourist. Only he could speak some english. The food included purple rice (healthier than white rice), eggplant with two kinds of tasty sauces, beans, very tasty mushrooms and soup with tomato and green veges. All were cooked and flavoured to perfection. It was great value at just 15RMB.
I forgot to ask the guy if he minded if I list it on Happy Cow but I forgot, oops! As I said above, the shop is small so they probably can't handle a big group showing up and anyway they'd want to know in advance to know how much to cook. But if just one or two people you should be able to show up just before 7pm to get a meal.
Cons: No menu to choose from - set meal at 7pm, Small area to eat in
