The Polo Bar
It really does not get any more fabulous and fancy than having the freakin' Polo Bar all to yourself. Ralph Lauren's preppy, leather-and-horse-filled favorite may not be fully open to the public just yet, but as of right now you can invite up to 20 of your closest friends for a well-curated private celebration complete with a bespoke menu and exclusive access to the ground-floor bar and Clubroom. Just don't forget to work at least one Shrimp Cocktail and one Ralph's Coffee Ice Cream Sundae in there.
The Polo Bar, 1 E 55th St.
