It's always New Year's Eve at Purga—the club has been celebrating it on every single night since it opened in 2002. The parties come with all the trappings of what's the biggest holiday in Russia—tinsel, silly outfits, champagne-fueled debauchery, and performances by dancers, singers, and comedians. As Purga's popularity soared, the mayhem was expanded to include Purga 2, in a different room at the same address, where a wedding takes place every Friday and Saturday night—you can even take a turn as the pretend bride or groom. Either way, keep in mind that this is Russia, after all, so the "face control" (door policy) is at a high standard: dress up. And you'll need to make a reservation to score a table.
