I only go to two Chinese restaurants in Pgh and this is one of them. They offer an impressive Vegetarian Menu with soy protein, wheat gluten, and tofu. They have a nice lunch special too that features several dishes from their regular veg menu, including vegetarian hot and sour soup.
The atmosphere is nice and the place looks much nicer inside than you would expect from the outside. The waitstaff is both nice and attentive and because I eat here a lot, they remember me.
My boyfriend is neither vegan nor vegetarian but almost always orders soy protein, his favorite is the Orange Soy Protein.
I recommend the Kung Pao Soy Protein for lunch and Shredded Heaven for dinner. Seriously, you need to try the Shredded Heaven. It's comprised of wheat gluten (seitan), tofu, bamboo shoots, and an assortment of other awesome things.
