Bachelorette Party Help

Ok, so my sister is trying to plan my bachelorette. I'm pretty sure we are going to do the Sex & the City tour and then I wanted to do dinner and a bar. I think she wants us to go to Mangia e Bevi for dinner and where to go afterwards is where we get stuck!

Can you girls recommend any good bars/clubs in the area of the restaurant? Someplace fun preferably! We are obviously willing to travel, but I guess it would make things easier if it wasn't that far. We will take any and all suggestions!!! The restaurant is 9th Ave at the corner of 53rd St.

Thanks everyone!!!
