If you get the chance to get into the Foundation Room, go! The view is fantastic and the experience is unique.
The first time I went here was about 5 years ago. I have gone every year since. It has changed a little over the years, but it is always a great time. The drinks are good, and surprisingly, not too expensive.
It is fun to people watch here ... cause you can run into all kinds of characters. People watching is a sport at the Foundation Room!
