Ask HN: Short list of the best hacker/entrepreneur/startup-related meetups to attend in NYC?

I'll be moving to NYC from Honolulu relatively soon, and I'm very interested to attend some good meetups or periodic events for hackers, entrepreneurs, and people running startups — that is, the kind of people who read HN. Of course I can and have Googled this, but it's hard to sort out the wheat from the chaff. Any suggestions for "the" meetups to attend to start networking? Thanks!
