First question …

Your first question is very broad. You may need to specify type of food, range, area. Regarding spas- spa de le la mer at the baccarat hotel, aire in TriBeCa, great jones spa, Guerlain Spa…just to name a few. Enjoy!

Taylor is right about dining choices in NYC. They are all over the place by cuisine, price, ambiance, etc..

I wanted to post a photo of 2 Brothers and this link has a story about $1.50 a slice pizza and a fancy bar that charges $1300 per pour for rare whiskeys!! ... If you wash down the slice of pizza with a shot of rare booze, that comes to $1301.50.

Best places to eat, but mainly is there a nice spa anyone recommends in Manhattan? I haven’t been there in years and will be soon, so I am trying to be a bit familiar with what places to eat and spa etc beforehand
