I found the 25PW gallery by accident. I was walking down Central Park West last November. Out of the corner of my eye, I saw people inside an empty commercial spot at the corner of Central Park West and W 62nd Street. They were carrying hammers and paintings. So, I checked the door, which wasn't locked, went inside and met Bess Greenberg, one of the founders of 25CPW, a non-profit that runs all the action inside this art gallery.
The fact that there's now a cool art scene on the Upper West Side alone is worth a visit – this kind of thinking usually happens in other neighborhoods. So, the curiosity factor alone should be enough to put this stop on your itinerary. But, that's the least of the many reasons to pay a visit to 25CPW. The best is whatever event is being featured on a particular day. They've all been fantastic.
