2. PH-D Rooftop Lounge at the Dream Hotel

Neighborhood: Chelsea
 355 West 16th St.

Technically an after-brunch party, The Dream Hotel's Sunset Saturday starts at 5:30 p.m. and ends at 10 p.m. But you can expect to sleep heavily after—no on to the next one here.

PH-D's brunch, like several others on this list, is marked by an air of careless extravagance and Chanel No. 5. Then the beat drops and the sax player blares away and the champagne baths begin. The chairs and tables vanish; fists ascend. Unfortunately, a few of those fists may pump, but don't let that ruin your buzz.

PH-D's off-hour party attracts a star-studded clientele, and subsequently, sprawling lines, so the door can tough. Our advice? Plenty of red lipstick on your honey and a convincing "money to blow" attitude.
