my husband and i will be taking my 10 year old stepdaughter and our 2 year old son to chicago the week after christmas. we'll mostly be hitting the aquarium and museums in the same area. i'm looking for a good hot dog place close by? our original plan had been a trip to Hot Doug's, but they are will be closed that week. since we'll have the kids and are just planning a day trip, we'd like to find something close by. suggestions??
