There's tons of places in NYC, but here's a few places I've been known to frequent<p>- Cafe Amrita, near 110th St and Central Park West. Generally has a pleasant buzz. I've noticed other techie types there, but not tons. They kick out the laptop crowd out on weekends, and at night they become more of a bar.<p>- Tea Spot, near MacDougal and West 3rd in the Village. A smallish place that has always been pretty quiet when I've worked there. NYU students are most of their customers, I reckon.<p>- Cosi near 23rd st and 6th Ave, in Chelsea. This is a chain, but this particular Cosi is well-lit, has good internet service, is large, and never seems to be very busy.<p>- As others have noted, New York Public Libraries are often great places to work. I sometimes sneak off from my office to use the Hudson Park Library, which is near Leroy and 7th ave in the Village. Its a tiny little branch library, but its quiet and the internet service is fast. There's a lot of little branches like that, look on the web site for locations.
