I'm going to Chicago at the end of June to celebrate turning 50 (yes...this is a celebration!). We are staying toward the south loop - one day will be spend at Chinatown/Navy Pier, one at the art museum, one at the zoo and of course another shopping! I need some feedback on some good, cheap, local restaurants. (a couple meals I don't mind paying a little more) Make sure you give me some ideas for Chicago pizza. Thanks for your help!
