The Top of the Rock Observation Decks only re-opened late 2005.

This is nowhere near as crowded as the Empire State Building.

Initially opened in 1933, it consisted of the 69th and 70th floors. It was originally designed to resemble the upper decks of a 1930s grand ocean liner, gooseneck fixtures, and large air-conditioning vents intended to look like the stacks on a ship's deck.

Top of the Rock is a 3-tiered observation deck on the 67th, 69th, and 70th floors of Rockefeller Centre (the upper decks 260 m above the street level you get an unobstructed, 360 degree view of New York City). Enter on 50th Street between 5th and 6th Avenue.

Once up to the viewing decks, the first two levels have a low wall with large Glass screens which enable you to get great views and photographs, there are reasonable sized gaps between the screens to enable cameras to get clear shots.

The top viewing deck has no screens, just the wall and a fantastic view of Manhattan .

Unfortunately you do not get an unobstructed view of the Chrysler Building, but you get a great view and an ideal photograph backdrop of the Empire State Building, and you also get an impressive view of Central Park, not to mention panoramic views of Manhattan and beyond.
