I'm guessing, by your username, you're about 24 years old. In that case, I'll step in and recommend some good clubs/bars.

Check out some of these places like Vision, The Apartment, and Leg Room. Leg room is on Division, which is a city block of clubs. It's usually packed with people on Friday and Saturday nights. There's other good places there on Division like Funk and Bar Chicago. Mother's is right across the street and isn't too bad in their downstairs section, in the back. (It's sorta big)
Let me know if this is your sorta thing- I have a lot of friends in the industry that would be willing to help someone out for me.
