Walk the High Line on the West Side if the weather is nice! This above-ground rail track has been converted to a walkable park, with some vendors along the path, and multiple points to get on or get off. Most importantly, it ends in the best beer garden ever: The Standard!
We like walking all over Manhattan, though often find us asking ourselves "Where the heck is closest Shake Shack?" Fortunately, there's one right next to the wedding venue and hotels, in Grand Central!
