Maxim is pretty good as far as Chinese grocery stores go. Another store nearby is Kam Sam, think the competition got them to improve. I've found their groceries and frozen foods tend to be less expensive and selections are similar. Don't know about the meats, seafood or veges, what I usually need I can get at Safeway. But for specialty foods like pork buns, potstickers, tofu, Chinese snacks, soybean milk & ingredients for Asian recipes this is the place to go. Don't mind the cashiers, they don't seem as friendly as at Kam Sam, but they're not as rude as what you'd often find in D.C. or on the Metro.
