Pretty excellent! I went with a large group, and we over ordered, so I got to try a lot of the menu. Most things were pretty spicy. I think my favorites were the Green Chile Boiled Fish, the cold garlic noodles, the boiled beef, and the Ma Po Tofu. We also tried plum juice to drink, which was unusual and smoky tasting. We spent about $25 per person, but we really ordered too much, we could have ordered two or three less entrees. Entrees ranged from 15-25, but were large sharing portions.
We had to wait about 30 minutes for a table, the place was packed, and seemed to have mostly Chinese customers, which I think is a good sign for authenticity!
I'll definitely go again!
