Bangkok used to be noted for its wild all night massive party clubs, but this has changed a bit over the years. With a maximum 2am closing time in effect for most legit spots, it's no longer party until the sun comes up, and additionally, young Thais have taken to frequenting smaller and more intimate venues as of late, so the big massive clubs aren't being built anymore, but in their stead have come a great selection of places to dance and party.
Undoubtedly, the hottest club right now is the wild Sing Sing Theater, a Shanghai 1930s fantasy that fuses theater with dance club. Also popular with the highbrow crowd is the new Club at KOI, an internationally acclaimed fashionistas paradise (with branches around the globe), which occupies a magnificent spot high above the city on Sathorn. Those who want a big party experience head to the happening Levels Club over on Suhkumvit Soi 11, which is one of Bangkok's hottest party spots, along with nearby Sugar.
Other happening openings include Beam, Demo, and the popular Violett over in fashionable Thong Lor, all of which have DJ's spinning house, techno, and hip hop to go with the great mixologists at the cocktail bars, and are wildly popular with the young upscale Thai crowd.
Of course there are still some of the top longstanding clubs in other areas to go to as well, like the famed party venue Route 66 on RCA (Royal City Avenue, same venue as Onyx). Back over on Sukhumvit, the underground club Glow is famed for its late night parties.
Wherever you choose, you are guaranteed a good night out with all the Bangkok dance clubs have to offer.
