Chicago advice

Heading to Chicago in two weeks for business. Ill be there about 7 days. Ive read the reviews , and gathered that it's low mileage and expensive. Id like to hit a couple places, just to say ive been there. Being from the south ive already been spoiled by all the club's around here. I was curious if any of you had some opinions/advice on some places you'd recommend or been to. Thanks in advance
