Just no.
This place does not have an actual menu, in English or Chinese. They have little placards on the wall with the names of dishes in Chinese but those don't have descriptions of the food or tell you what anything costs.
I came here for the first time on a Sunday night and the service was terrible. The woman at the counter has godawful memory and honestly seemed kind of sexist. I stood at the counter for 10 minutes while she shouted across me to double and triple and quadruple check her other (male) customers' orders. I didn't see her doing this to any guys.
I ended up just leaving due to the service and the fact that they ran out of baozi (AND noodles) but my roommate got me some of their dumplings later. They were so-so. Not particularly good or bad: they were just run of the mill dumplings. I get that handmade dumplings are hard to find around here but anyone who's been to northern China or even a decently sized Chinatown will tell you they've had better. Hell, my roommate and I can make better ones at home when we have the time.
No menu, bad service, and running out of multiple main items before 7pm? I can't see this place staying open for too long if it keeps this up.
