Well read the NY Times and other NY specific newspapers. Know what's going on. The area you go to, google it and look up funny facts and other information.
This way you have plenty to talk about.
Ask her some questions with sexual tention if you feel there's some trust and connection. Like a question game from Mystery where you're not allowed to ask the same question as the other just did, and they have to be interesting and not the usual boring stuff. "Where did you come from?" etc.
You can ask how many boyfriends she had and if she plays ball and asks stuff like that too, you can go more into detail of favourite position etc.
Also, KINO kino kino! For me the difference between friendszone is kino-ing the shit out of eachother. Do some basic palmreading (it's simple, no really.), pull her hair and ask if she likes it (also from Mystery, there's a story behind it) etc.
And be relaxed, have some fun.
