Asian grocery store near Oak Park?
It totally depends what ingredients you are looking for. Even in Chinatown, you may not be able to find what you want. Since you mention Oak Park, you may want to look into Chicago Food Corp on Kimball just n. of Belmont. from Oak Park, it's a pretty quick drive on side streets heading east. Worth the travel for the selection they have. I normally stock up on major pantry staples from cfc or tai nam or super h, then in between stockups, I supplement at the Tony's in North Riverside. BIG Asian markets in or around Oak Park tho, I can't really think of any that are notable at all.
