There's a sequence involving a brownstone on Gramercy Park (at around 21st St). I once "dated" someone who owned a coop on Gramercy Park in the 70s, but I didn't recognize it. Is the part about keys to a private part of the park true? I doubt it.
There was a shot of Pete's Tavern, in the East Village, which I recognized. And I thought that a bar scene looked like the inside of Shakespeare's, as I remember it from 1978. I had another "boy friend" who played for tips there. I couldn't find it online, but there is a Shakespeare's pub crawl (like the "World's End" movie). The movie has a line about East Village hookers, but the area has a large LGBT community, and the Ninth Street Center was located there until the early 1990s. It would have been a cute idea to shoot at the Half King, Sebastian Junger's restaurant on 23rd in Chelsea, but that's way over on the far West Side. If a director wants the best gay venue in NYC, try the Therapy (on two levels, with a skylight) in Hell's Kitchen. Of course, two village bars, Julius's and the Stonewall Inn, have appeared in some films.
The screen shots of social media sites appeared to be patterned after Google+, not Facebook.
A companion film could be Jason Rosette's black and white documentary in 2000 "Book Wars" about NYC street used book vendors, which I saw at the University of Minnesota years ago.
