Gyotaku is a Japanese art of creating a print from nature, typically, of a fish. After ink is applied to one side, paper is laid over the fish and rubbed to transfer the image. During my grade-school years I attempted to make a gyotaku print during a summer science course; the instructor fared better than the rest of us in applying sufficient, consistent elbow grease.
I also remember that our fish were very smelly, more suited for the classroom than the dining room — which, as you'd expect, is far from the case at the restaurant whose signage is shown here. Can you name it? (Please post your answer in the comments.)
