Old Chicago is a fun place to go at night. Many people meet up there to casually chat and have appetizers and beer. The beer selection is good and the appetizers are good. I've only had a real meal there once, and it seemed decent enough. It is much more of the kind of place you go to meet up with old friends. Don't go there for serious conversation -- it can be pretty noisy! It also can be pretty crowded at night and you might not get the best service, but most people going there in the evening aren't there for the food/service. The staff is very friendly and they seem to enjoy the crowds and the fun spirit of the place.
