Our family has been going to this restaurant on-and-off for a couple years now. Heads-up: It's a bit tricky to get to if you're driving north on Lake City Way, you'll see it on your left, but you'll have to pass it and do a U-turn to get back to it.
For a Chinese restaurant located in North Seattle, they aren't bad. We've had large family gatherings there with my gong-gong and po-po without much problem. A definite welcome addition considering the other options (Chiang's, T&T Seafood). They have one huge room which seats plenty of people.
They attempt to have a wide variety of more authentic Chinese food (including xiao long bao zi, mmmm), not just your average Chinese-American stiry-fry neon batter-coated stuff. And do they pull it off? Eh, for the most part it's pretty good, but nothing fantastically outrageous if you're asking me.
My last visit there was pretty bad though, hopefully it was an anomaly. After waiting more than half an hour, it was apparant that they forgot our order. DOHP. When it finally came, the niu rou mian was pretty bland, had to add salt and soy sauce to bring some flavor to it. Ouch.
