Madison Square Garden, New York City
Normally people go to the musicals and theater, I don't like so much of that.
So I prefer to watch a NHL game (Let's go Rangers!) in Maddinson Square Garden. Don't miss the garden!!! There are plenty of event there to see.
Check if there's a concert or a sport-event at Madison square garden. There is also a huge selection of musicals and stuff like that.
Go visit one of the many museums like the Guggenheim or the Metropolitan museum of art (more info on Metropolitan at www.metmuseum.org)
Or go and see David Lettermans 'Late night show' at CBS.
Check the Madison Square Garden, when I was in NYC, there was the concert of Elton John. It was really fine and we were drinking champage with strawberries. 7-th Avenue and 32nd Street, Manhattan
