Located in the heart of the Design District, this is the only dim sum restaurant I know of where you can dine outdoors. You can watch the dim sum being made.
My favorite menu items are the garlicky green beans, the cucumber/fresno chili salad, the seafood gyoza, the shrimp toast, and any of the xiao long bao (soup dumplings). There's usually a line but it's worth it.
Also, this place wins the prize for Cutest Logo Ever.
