I will be changing trains at the Amtrak station in Chicago, and it looks like I'll have some time for lunch there. Shall I eat in the station? I'd rather go somewhere within walking distance that has some local color or maybe ethnic food. Isn't the art museum nearby? I'd like to stop in there if there's time, so a place between there and the station would be great. In addition to location and description of food, pls also indicate price range and days open, if you know. Thanks!
