The venues of ROCKIT RANCH PRODUCTIONS have long been known as hot spots for celebrities. Robin Thicke, Katy Perry, Kanye West, Nelly, and Miley Cyrus have all busted a move at the Underground Chicago {theundergroundchicago.com}. And Kate Upton has graced the nightclub with her presence, as has Lebron James. Over at SUNDA {sundachicago.com}, musical legends Jimmy Buffet, Barbara Streisand, and Steven Tyler have all stopped by, as have Mark Wahlberg and Michelle Obama. And there’s a chicken-and-egg mystery to be solved about star-laden ROCKIT BAR & GRILL {rockitbarandgrill.com}: Do celebrities come because of the happening vibes there, or is the hip scene a result of all of the celebrities that visit?
