It's a wonderful 7th floor rooftop that has views of the Empire State Building and the New Yorker Hotel.
The building that it is in also has 2 studios that are on this site as well. Either one of them can be used as a holding studio for an additional $2000/day.
Check out the links below to see some videos of the rooftop:
