Apparently the basement of the “Castle on the Park” has been converted into the “yes gallery,” which strikes me as slightly more appropriate use of the space than the obvious choice of a bodega or paid bathroom. In all honesty, I was more interested in checking out the inside of the building than the art, but last I heard, they were trying to rent out the basement to start-ups for the lofty sum of $10k a month, so I guess this means it's some damn nice art (or at least expensive enough to pay the bills).
When I started eyeing the staircase to sneak upstairs to check out the rest of the building / find a place to pee that wasn't a portapottie, some official-looking dude sitting at a table complete with a matching MacBook shot me a death stare that screamed “if you do it, I'm going to beat you over the head with a three thousand dollar paper cylinder.” So yeah. if you want to know what it would be like to ludicrous amount of cash and live in a church, might I suggest devising a way to distract the staff first.
