The Rockefeller Center is a large complex consisting of 19 buildings between 48th and 51st streets.
There is a shopping mall, restaurants, etc. in the complex. Organised tours provide detailed information about the Rockerfeller family and how the complex was built in the 1930th.
The highlight is the view from the observation deck on the 70th floor. It gets really crowded up there, so you might want to either go early or rather late.
