Perhaps South Beach's most enduring boite, Mansion is prime real estate for visiting celebs. You can dance if you want to - if you can find the space. The soundtrack varies from the latest in hip-hop and pop spun by star spin doctors such as DJs AM and Irie, to live performances by Jamie Foxx and pretty much any celebrity who fancies themselves a singer, scratcher or shouter. The typical Mansion crowd likes to strike stationary poses against whatever free space they can find. Everyone from Robert Downey, Jr. and J-Lo to Britney, La Lohan and Paris Hilton have lounged on the VIP couches while the rest of the crowd cranes their necks to catch a glimpse. You may be tempted to think it's all A-list in here, but the throngs of hopefuls lined up on weekend nights means that mere mortals (albeit well-dressed ones) have a more than decent shot at getting in, too.
