Try Golden Dragon on Hillsborough Street right accross from NC State University. All the chinese grad students from the college of engineering go there and it is AWESOME! Get the tofu vegetable plate with lo mein - it was $3.50 last time I was there and enough food for 2 people. Best lo mein I have ever had - perhaps the best single food item I have ever had - I think they sprinkle crack on it it is so good. One of the few places I'm willing to go out of my way for and deal with finding parking around the college campus. All takeout menu.
I know there are lots of nasty crappy chinese buffets. The skill comes from finding the good one(s)!
