5. Grand Central Plaza
Located at 622 Third Avenue at the corner of 40th Street, this park offers a bird’s eye view of the street below. It is one of the more unusual public spaces in the city because it sits on top of a two-story building, also a rarity in Midtown Manhattan. Several stationary and moveable seats scatter the space and in good weather, a coffee kiosk opens in good weather to serve reasonably-priced coffees and snacks.
