Food quality is not great, not the absolute worst. If you're not there at the early morning special when prices are $2.30/dish, it's not worth it.
We ordered extra dishes (pork buns), which never came, even though we asked 4 times over the course of 40 minutes. Each time the server assured us that it was just about to leave the kitchen. The dishes they have were clearly purchased and heated to order, which lots of other restaurants don't do.
