3. Ajna 

Neighborhood: West Village
Address: 25 Little West 12th St.

This day and night brunch party (run by the famed Koch brothers) was once held in the Oak Room at the Plaza Hotel. That is, until they were kicked out for soiling the hotel's classy reputation (with champagne spray and bodily fluids, most likely).

Now the brunch extravaganva has found a home in Ajna (the former Buddha bar), where the DJ pumps deep house and dubstep for trust fund babies and socialities who barely manage an eye twitch at the $200 fee for the fiesta. But it's a small price to pay for the perfect atmosphere for mistake-making and booty-shaking during normally tranquil afternoon hours.
