The Polo Bar
For an extra posh and preppy affair, you can always count on the Polo Bar. In fact, booking a private event at the hot spot is probably the easiest way to get a reservation. While there are quite a few buyout options, we'd recommend the festive scene inside the richly outfitted Equestrian Room, which is basically a Ralph Lauren catalogue come to life.
