To really do up the day right, plan a brunch or a dinner party on this Brooklyn garden rooftop. Without many gardens in New York's urban jungle, Brooklyn Grange is utterly unique. | Photo Credit: Emmy Hagen
The most lovely rooftop bar and restaurant in Chelsea (Manhattan). The Gallow Greene. Make reservations to avoid a long wait. Also near the Highline, Chelsea Market, and the new Whitney Museum if you need somewhere to eat after doing those. Go for brunch or dinner. It's like Anthropologie meets a restaurant on a rooftop. A must.
