This location is almost as good as the original in Squirrel Hill, and is one of the best places to get authentic Sichuan food in Pittsburgh (probably in all of Western PA).
The knocks are the ambiance (the location used to be an Indian restaurant and they didn't change a ton) and the service (which is slower and a little more disorganized than the original), but the recipes are the same and the food is great.
I'm a big fan of the Chengdu style chicken and the double cooked sliced pork belly, but if you really can't handle spice, try the "Chicken with Basil" (an authentic but non-Sichuan dish with a bit of sweetness, garlic and, you guessed it, basil).
I've gone here for lunch meetings, social dinners, and take-out, and would (nay, will) happily return.
