In NYC, you can easily get wherever you wanna go with the subways. NYSE and Gazebo are both in lower Manhattan, so it's probably just a 5-10 min subway ride- I can give you easy directions if you show up. Also the area is safe, even on a Saturday night at 2am there are still tons of people/cops walking around so you not gonna get randomly jumped in an alley like the movies. Just don't look like a bitch and people will leave you alone.
