Top of the rock - Rockefeller buildingEmpire state building.These are the two that I know of.
Well, there is Rockefeller Center. There is an observation deck at 30 Rockefeller Plaza, which is the GE Building and its the headquarter of NBC Television.Good luckNative New Yorker
rockerfella centre is great, when you go up during the day, you can do the touristy photo opportunity by pretending to put your finger on top of the empire state building, great photo.
30 Rock is by far the BEST! There are multiple levels and you can view indoor and outdoors. It s an amazing feeling standing outside on one the tallest buildings in the city overlooking all of Manhattan.
