We visited the Rainbow Room at 10pm on a weekend. The security guard at Rockefeller Center directed us to the correct elevator, and the usher on the 65th floor showed us into the bar area. All drinks are $18 to $25 apiece, but our two drinks earned us unlimited time in the breath-taking viewing areas around the outside of the lounge! There is a walkway that goes around 3 sides of the building, with some seating available. The lights and buildings of NYC are just so impressive from here! My understanding is that it costs about the same to take the "Top of the Rock" tour, and this bar is just a floor or two below that tour location - so I like the fact that we got a drink for the price, as well as the view!
