...if you don't know what for, then I can't help you.
This was a fun one on several levels. When I pulled up, I was surprised to find that the front parking lot was in use as a flower nursery and market. This proved to be useful, though, because I could park right along the side of the building among the customers. No one gave me a second glance as I walked around the back to an open door, and even though I kept a watchful eye out front while inside, I didn't see a single person bother to look up from their shopping at the large, decaying Art Deco building right behind them.
Even though the dining area in front is the most obviously photogenic part of this place, I particularly enjoyed the convoluted (and sometimes very dark) industrial areas in the back. Every area had unique architectural quirks that made just about every room worth checking out, even the enormous, rather disgusting freezers and the pitch-black warehouse areas at the very back.
As always, thanks for looking!
