This doesn't seem to be the type of question that typical tourist guide-books answer: Where are the nicest grocery stores in the area? Are there any much nicer than the chains I know, like Whole Foods and Trader Joe's? I do know Andronico's.
Also, what is the nicest Asian grocery store? Variety of items and cleanliness are more important to me than cost. I really like Super H Mart, but I don't think you have any of those.
