Holes on the wall
How often do you get to a cafe with part of its walls like this?
To be honest I had no idea what was this. But I love literature, and I am always thrilled to spot references to it in places I do not expect them to be at. A bit of skimming tells me this is from a novel called Holes by Louis Sachar. It won the 1998 National Book Award for Young People's Literature, and was adapted into a film in 2003.
