7. 6 1/2 Avenue
In Midtown, 6 ½ Avenue is a series of mid-block crosswalks from 51st Street to 57th Street between Sixth and Seventh Avenue, connecting arcades within the dense buildings of Midtown. They are the unique children of the ongoing public-private love affair dotted around New York City called POPS, privately owned public spaces.
One note: even the atrium within the Parker Meridien Hotel (above) is technically a public space although much of it has been taken over by various concessions like this hotel bar and café.
