Truly one of New York's Hidden Treasures. I met up with some friends at the Boat Basin a few weeks ago, and while walking West on 79th street began to think that they were playing a joke on me. The large open area is actually located underneath the WSH, and you practically have to walk onto it before you see the staircase leading downstairs. Food is your typical bar food (Burgers, Nachos, etc), but you have a view of the river, and one of the largest outdoor bar areas in all of NYC.
Pros: Great View, large Open area
Cons: A slight hassle to get to
