Designed in homage to ocean liners and first opened in 1933, this 70th-floor, open-air observation deck sits atop the GE Building, the tallest skyscraper at the Rockefeller Center. Top of the Rock trumps the Empire State Building on several levels: it’s less crowded, has wider observation decks (both outdoor and indoor) and actually offers a view of the Empire State Building itself.
If you don't have under-21s in tow, consider ditching Top of the Rock for the 65th-floor cocktail bar , where the same spectacular views come with well-mixed drinks... at a cheaper price than the Top of the Rock admission.
