In Vegas, the tables never sleep, but almost everything else does -- win big at 8:30am, and you've got nothing to blow your wad on but gift-shop shotglasses and plates of rubbery eggs. For a magical ride at any hour, hit Puff.
Just off the Strip, Puff's a massive, harem-themed bar/club/lounge/live music space that stays open 24/7, allowing it to boast Vegas' only 4-6am happy hour (which you'd call sleeping hour, if you weren't grinding wild-eyed on "casino oxygen"). Morning, noon, and night, you'll have the run of curtained-off, pillow-strewn boudoirs, multiple bars & dance floors, stripper poles, an outdoor patio, and a full-size hot tub you're free to climb into, provided you don't mind hundreds of people witnessing your nutty behavior. As for consumables, there's a full tapas menu (crab puffs, pork kabobs, etc), but the mainstay's hookahs: 40 flavors from cardamom to bubble gum, whose smoke is filtered through premium booze -- like your college bong experiments, except backed by millions of dollars, and not left to breed intelligent life after failure.
Puff'll kick off with the 36hr, Friday-to-Sunday Puffapalooza: bands, DJs, go-go dancers, fire breathers, aerial artists, and midgets walking around with hors d'oeuvres trays on their heads -- because besides big winnings, nothing makes you feel like you're flying higher than watching a dude roll deliciously low.
