It changes each time the story is told.

There was a mountain loo with a glass front on the slopes in Laax. (Photo removed.)

IIRC (and I may not, I was ver ver drunk) there was a bar in Chapel Market with a window above the ladies washbasins where one would be face to face with blokes using the urinals on the other side of the wall (from about waist up, not full frontal).
I don't know if it was mirrored on the other side though.
What cuisine was the restaurant?
