Newly single here. What are the best gay bars in NYC?

I coming around with my breakup with a guy who is bi (he's now with a woman - let's see how that lasts) and it's time move on and get back on the saddle.

I'm in NYC and I'm down to meet up with some guys in some fun bar. What are some of the best gay bars in NYC?

*I'm look for both some casual (where you can drink and chat with guys) as well as looking for some fun :)
