LOWER EAST SIDE. If you're a fan of Warhol, this spot on the Lower East Side is a must. Indeed, the foil-covered walls, a freight elevator entrance and scores of beautiful patrons do their best to recall the heyday of the legendary Factory. Adding to the place's kitsch quality are their potent potables, most of which are named after streets on the LES. As for dancing, if you're so inclined ­ And at this hour, who isn't? ­ just head downstairs, where the talented DJs work the late night crowd into a frenzy with their awesome mix of disco and house beats. TRAIN: J, M, Z to Bowery

THEATRE DISTRICT. Beautiful people mingle, order expensive drinks and dance among hundreds of others in this hip club. Music spun by a DJ throbs wildly as patrons strain to hear each other. A happening place to watch people and have a great time. Among the famous seen here are Bruce Springsteen, Elton John, Michael Bolton, Stevie Wonder and David Bowie. There's also top floor indoor-outdoor terrace, which accommodates 500 people. On-site ATM. TRAIN: C, E to 50th St

MEATPACKING DISTRICT. One of the city's top clubs regardless of who's keeping score, the place "where house music lives" is indeed a primo spot to be in the Meatpacking District once the midnight hours roll in. The music ­ an innovative, global montage of everything from Afro-Latin and soul to techno and nu jazz ­ is a big draw, of course. The scene (sexy decor, a sunken dance floor, and cozy brown and beige banquettes) generates a fair amount of its own buzz... as does the beautiful, 20-something clientele. TRAIN: A, C, E, 1, 2, 3 to 14th St; L to 8th Ave

FLATIRON DISTRICT. Boasting enormous, sexy digs and a stunning variety of eye candy, this Flat Iron club certainly sees its share of big crowds for each of its themed weekend parties. Krash Fridays bring in mostly gay crowds for a long night of revelry and loud music. Tantra Saturdays draw mixed crowds thanks to world-renowned DJs who spin everything from hip-hop to pop, live music, bottle service and VIP tables. Sundays, then, are given over to Latin and Reggaeton acts, and the scene goes hard and heavy until the wee hours. TRAIN: F, V, N, R, W to 23rd St

GARMENT DISTRICT. Barry Manilow may be alive and well ... But don't plan on catching him at this cavernous Garment District Club, which books some of the city's hottest Latin bands each week. Indeed, if you like to salsa, merengue or bachata, this is the place to do it (if you want to learn, stop by on Tuesdays between 7pm and 8:30pm for free lessons). As the night wears on, especially on weekends, the pace and pulse of the music picks up significantly, and you'll find it's easy to burn calories in the disco room as house, R&B, hip hop & Reggaeton pound the sound system. TRAIN: A, C, E, 1, 2, 3 to 34th St-Penn Station
