This is the area where the financial district meets a more touristy area. Attractions like the Charting Bull and Wall Street draw in people and there can be hoards of people at once, especially surrounding the Bull.
At the same time, you have the huge National Museum of the American Indian and the area is a short walk to the Staten Island Ferry terminal.
Plenty to do and see; just gets very busy.
The Bowling Green metro station is right in the centre and there is a Starbucks almost immediately opposite on one side of the road.
