China Lin is my go-to local place for Chinese food. It is not upscale gourmet food, basic Americanized Chinese food, but good. The portions are huge and the family is so sweet, and they remember regulars like me. Once I ordered from a different address, and they said, "Oh? You move?" - LOL.
The steamed dumplings are good and I also like the crab rangoon. A good entree is the sweet and sour chicken. My Dad likes the General Tso's chicken, although his order was not super spicy, so you probably would have to ask for it spicy.
I live in Lawrenceville and it usually gets here in 20 minutes, although they cook everything to order. They delivery guys are polite and very nice, too, and come right up to the door.
