Chicago's hottest nightspot is luring crowds with shimmering white powder (the legal kind). At the 4,000-square-foot dessert bar Sugar (108 W. Kinzie St.; 312/822-9999), beehive lamps and marzipan-textured walls are a kitschy homage to all things sweet. Go-go dancers gyrate on the bar, and the waitstaff wears candy-colored Pucci. Your dentist doesn't need to know.
