I have been to the top of the Empire State Building, and I have to say that the Top of the Rock is a much better experience. Being able to see the ESB and the rest of NY from up high was really nice. The overall experience was a good one. From the lounge area to sit inside, to the spacious outdoor decks for viewing, I never felt crowded. Multiple levels for viewing too, which was pretty awesome. Loved the experience, would definitely go again!
