Boat Basin is an awesome spot to hang out in the summer, regardless of the size of your group. The whole place is essentially outside, but sits underneath the West Side Highway right on the Hudson River, so there are areas of shade and areas of sun. Solid sandwiches, burgers, and seafood, and pretty good beer options. Get some afternoon day-drinks in the sun, and then watch the sunset over the Hudson.
