If you could use a laugh or two after a long conference day, Chicago has plenty of entertainment options on the lighter side. Check out the comedy listings at Time Out Chicago for a taste. Also consider one of these two Chicago favorites:

The Second City

A top comedy club in Chicago, Second City launched the careers of such big names in comedy as John Belushi, Mike Myers, Bill Murray, Gilda Radner, and more.

Blue Man Group
