My boyfriend and myself will be in NYC from 10 until 14 December 2009 and would like to go out in trendy clubs and bars and also go to restaurants where New Yorkers are regularly going. We love going to musicals, having a drink, listen to live music and enjoy a good meal in a trendy restaurant.
The meatpacking District attarts the dance and food crowd with Sans Cubano being a good lark.
Irving Place has loive gigs and dance nights, check out their listings.
Public restaurant is trendy-book though
Can't go woring with anything on the lower east side for trendy and happening. Hotel on Rivington Street bar attracts the crowds,
On the Hudson river side, the Hotel gansevoort is very trendy-rooftop pool side bar. Good restaurants in that area too.
Nileguide has a listing of cool bars: http://www.nileguide.com/destination/new-york/best/trendy-bars
Finally, check out Foodand wine.com and do a search in their directory-they sometimes list latest trendy places before the mass word gets out as does Thrillist.com about 7 years ago
