The workers here were really unfriendly, bordering on hostile. I think it was because I don't speak Chinese. I know it's imperialist to expect all the waiters in the world to speak English and be servile, and so I don't expect it, and I try to be humble when I attempt to communicate. But at this place they wouldn't even return my smile. There's a certain brusqueness to service people in China which I respect. But these people took it to another level. And it's also fine to refuse to serve someone (especially annoying tourists!), but it can be done politely or rudely. They did it very rudely. And when I returned to try again (this time with a Chinese friend) they had closed-up early. So we went elsewhere (without trying the food) and I recommend you do the same.
Cons: Unfriendly workers
