Has no sign outside, so you might miss it, but if you do happen to find it, you will feel like you have walked into the 1920's. Its very chic, with Black and white marble decor, candle light and ambience to go with a great list of cocktails and whiskeys etc.
I have old friends in San Francisco who grudgingly tell me that the High Line is everything that's wrong with New York. Well, too bad. To me, it embodies a culture that's constantly reinventing itself: a defunct elevated railway that was becoming a burden to the city ("we used to climb up there to throw garbage bags full of rotting Korean food at the Hasids!", noted a successful photographer's assistant) becoming a startling example of urban greening for the public good. The expert landscaping makes it feel like walking on a Montauk beach - but a stone's throw from some of New York's most progressive galleries and hotels.
This is a pro tip, but also a summer tip, take the ferry from Lower Manhattan to Rockaway and spent the day. The beach is great and the area is impossible to gasp that it's 30 min from Manhattan (without traffic) - Eat as many tacos you can, cause it's the best in the state of New York!
