Any suggestions on things to do in Chicago this weekend? I'll be going to see New Pornographers at Metro on Fri night, but that's about all I have planned. Good bars, parks, pizza, sights, etc.? Staying right downtown by the Navy Pier (fiancee's work is sending her for a conference, not much choice as they picked/paid for the place). Neither of us have ever been, and not really sure where to start. Thanks
