I didn't see any mention of the "The Blue Unicorn" located in San Francisco in the mid sixties. We were driving around the city. We got very hungry and saw the "Blue Unicorn" sign. We figured it was a good place to stop and eat. It was a narrow room with a small stage at the further end of it. There was a folk singer playing that night on small stage. We went to the food bar and all they had to eat was half slices of french bread and a half-stick of butter for fifty cents. Of course they had coffee to drink as well. While there I saw a girl come in dressed in feathers of all colors like Janis Joplin would dress at times. The customers were more like beatniks than hippies. They had very long hair, plaid wool shirts and looked more like lumberjacks than anything else. It was a very unusual place.
