At Le P'tit Caribou in Mont Tremblant, Quebec, the parties are anything but petite. Patrons are known to dance on the bar, disrobe, and literally swing from the rafters. The night ends at 3 a.m. with a sing-along to Kenny Rogers' "The Gambler." "You can't come in here and have just one drink," says co-owner Sébastien Turgeon. "It's hard on the liver, but we're here to entertain."
