My wife and I are coming to Chicago and I want to do a nice lunch for her birthday on a Saturday. We are staying near the Loop and would like to stay in the Loop, River North, Mich Ave area. Our 10 year old son will be with us and is very accustomed to eating well in nice places. I would like to stay away from the hotels and am looking for something eclectic with a good wine list. Any suggestions are appreciated.
