I was able to see the observation deck for the Empire State Building and the Top of the Rock during my recent visit to NYC. I had a much nicer experience at the Top of the Rock. The elevator ride to the top featured a glass ceiling with projected images of the building's history as you ascend. There's a fun light room sponsored by Target where different lights follow you along the walls as you maneuver your way around the room. The view is breathtaking and you see the beautiful ESB in the distance. At the ESB, you have to wait a long time just to get to the elevators that take you to a waiting floor where you wait even longer before you take another set of elevators to the observation deck. There was not much waiting at the Top of the Rock and the recent rennovations give it an aesthetic edge over the ESB as well.
