I've heard "The Underground" is a fun spot-- with good food and drinks, which is always a plus.

It's too bad, when I was younger I was actually able to climb to the crown of the Statue of Liberty, but they don't let you do that anymore. Ellis Island is still open for visiting though, if you want to get your share of history. Other options are Times Square for shopping and broadway shows, Coney Island during the warmer months, and definitely a walk along the Hudson, no matter the season.

It totally depends on your taste. If you are into Art, the Met couldnt be more iconic. But that might not be for everyone. We have a great Natural History Museum (think Night at the Museum), but again if that isn't your thing I might skip it. But I think everyone should go up the Empire State at least once in their life. And Times Square at night is certainly a must-see. But the list goes on and on. so if you reply with your interests maybe we can help more!
