We had dinner this evening at a new restaurant in Chinatown called Szechuan Tasty House located at 902 Arch. They have been open about a month and specialize in Szechuan spicy chinese food -- a rare find even in Manhattan. My wife is from Hong Kong and has family in Vancouver so we've both had our share of tasty chinese cuisine.
This place was terrific offering truly authentic versions of traditional dishes. They seem to have beer and you can bring your own wine. The obstacle is that most of the traditional dishes are only on the chinese menu -- and even with a native Chinese reader there are a lot of local terms that don't precisely describe the content of the dish. We went with recommendations from the staff based on descriptions of what kind of food we wanted.
We had Szechuan string beens (sei gwai dau), beef tendon and stomach appetizer (fu chai faai pin), a spicy chinese version of Italian pasta (dan dan mihn, and the standard seui chyu nauh yuhk - beef with a ton of chili powder on top in a red broth with vegetables.
