Su Xing's food is absolutely wonderful. It's so good, in fact, that you'll forget you're eating at a Chinese restaurant that doesn't serve any meat! Some menu stand-outs include the eggplant in garlic sauce and the vegetable and tofu mushu--the tofu is tender and has a consistency of chicken. The atmosphere is cute and the waitstaff is helpful. While the price is a bit more than most Center City Chinese places, the quality of ingredients more than makes up for it.
Pros: Quality of ingredients, breadth of menu, willingness to customize dishes
Cons: Service can be a little slow
