Summer in the city is great with the heat, humidity, random rain, and makeup melting off your face. But not having to wear a jacket and having an array of rooftops to choose from, makes it worth the literal sweat and tears. And the Met has one of the best rooftops around, featuring views of Central Park and its surrounding real estate, along with alcoholic and non-alcoholic drinks, small bites, and an annually changing art installation. Try to hit the rooftop before it closes at the end of autumn for a view of the multicolored trees--and to remind yourself what leaves look like before they disappear for six months. Entry to the museum is required to get upstairs. Expect long queues for the elevator at night and on weekends.
