Re: Chicago/Surrounding area
You should try Scores. It's a gown club. It gets busy late and on the weekends. being close to Ohare airport helps to drag them in. Avoid Skybox that's got LE activity. A club in Chicago downtown called Vips is like Scores and has a lot of money potential. It's also a gown club. You could also try the Pink Monkey downtown.

I liked Club O worked there for 3 years, kinda strict 3 song sitting limit, 3 drink limit but it keeps you focused on making money. Alot of my friends are at Atlantis now.
