To call this place a well kept secret would be n understatement.  I lived about a block away and around the corner from it for a few years in the early 90s and had no idea it was there.  It’s been there since at least the 70s (their web page is a bit vague on the history so I don’t know exactly how long).  I’m sure that says about as much about me as it does them, but still.  I just discovered it on a photo walk in December when I took this shot.
