Unfortunately, with so much security these days, all one can see is the exterior of the building. It is one of the most famous sights in New York City, though, and it is close to other several historical buildings. A visit is especially worth during the holidays, when the massive Christmas tree on Broad St. makes the block a more interesting place.
Pros: There is no cost to seeing the exterior of the building, close to several other attractions
Cons: With so much security, no visitors are allowed inside
