I've been to Qing Hua a couple of times because the dumplings are excellent. No complaint there: they're cheap and delicious. However, the service has been consistently terrible: very slow and inattentive. Today was the final straw. I went out to dinner in a group of eight. It took them ten minutes to take our order, and another thirty before anyone was served. I ordered boiled bok choi dumplings with mushroom.
My order never came. Ten minutes after everyone else was served, I asked a waitress what had happened to my order of boiled vegetable dumplings. She replied that they were unable to make boiled vegetable dumplings, as they exploded in the pot of water(?). Apparently, the waitress who'd taken my order didn't know this, and no one had bothered to tell me that I had ordered something un-cookable. I decided to not eat anything rather than risk another forty minute wait.
Conclusion: probably the most incompetent customer service I've ever experienced. Although the dumplings are tasty, I will not be returning.
P.S. Why can a dumpling restaurant not manage to make boiled veggie dumplings?
