It doesn't show from this photograph but this bathroom was the most well hidden bathroom I've ever seen in my life. It was in a restaurant, and when I asked where it was the waitress pointed to a wall with vase. I was a little shocked at first, but I walked towards the wall and there was a hidden corner right next to the vase. As I got closer an opening appeared near this corner. Next thing I knew the opening turned into a series of twists and turns and suddenly I was in the bathroom. I'm fairly convinced that this is exactly how Harry Potter felt when he was told to walk through a wall in a train station.
