Since opening in April 2000 in downtown Miami, Club Space has lured throngs of South Beach regulars across the causeway. Created from four warehouses, Space, true to its name, offers more than 9000 square feet of dance floor. The door staff -- firm, polite, and unhindered by the essential Beach ego -- remains as cool as the cavernous joint, which stays chilled even when fully packed, thanks to a powerful air-conditioning unit.
