As a visitor from LA, it's hard to say any Chinese food in Pittsburgh is good. With limit choices, I should give my highest score to how lee.
Some food there remind me the time back in LA. The spicy chicken is a must try entree here. Among others, lumb and double cooked pork slides are awesome.
Service is so so but not bad. You know that's very common in a Chinese restaurant. Lunch special is very affordable.
If it's in LA, I may only rate it 3-3.5 or so, but in Pittsburgh, it's definitely 4.5-5 given the limited choices here.
