My favorite Chinese place in the Triangle is Pao Lim on the Durham-Chapel Hill Blvd (aka 15-501 Business).
The food is primarily Chinese with some Thai and Indian dishes. Everything I've ever had there is beautiful and delicious. I especially like their mu shu pork, mu shu vegetables, lemongrass tofu, and salmon with greens. For starters, try their dal soup. I usually also get brown rice and jasmine tea.
I like the fact that not all of the food is fried and swimming in thick sauces. They do not use MSG according to a menu I saw and the food is freshly cooked to order.
The big bonus to Pao Lim is that I can walk there from my house!
