Agree with
@samspade. They're pretty much everywhere, and it just depends on what you're into socially and your taste in women.
Even though, for example, some of the most attractive women from NYC, that are my type, tend to come primarily from Astoria/Queens, Yonkers and Staten Island, and some from Brooklyn and Manhattan, when I go into the city, I usually head to the Meat Packing District for the nightlife, hit Yonkers up to Tarrytown for coffee/brunch daytime dates and such and almost always avoid Midtown.
MPD has some truly great restaurants, rooftop lounges & night clubs, is pretty central to the 5 boroughs and tends to attract those sexier women with their little tight dresses, clutch purses, high heels, etc. from all over the city.
Every time I go to Midtown it's fvcking green hair and nose rings. Lol. No thanks.
Hoboken on the other side of the Hudson has a decent night life with a lot of attractive women, and you can even roll through there at 8/9 in the morning and you'll see hotties crawling everywhere heading into work. years ago I used to work out on the streets for the power company. Every time my crew was sent up to Hoboken we would have ear to ear grins because we knew it was going to be a great day of eye candy and opportunty.
