I was just browsing this thread wondering if someone would beat me to posting that place. I found it and ate there back in the '70's, and it was still around when I was in Portland a couple of years ago. The name struck me as humorous (for a Westerner) then and I still have a business card from them that I took with me for the same reason you took the photo.

Does anyone who understands the language know what the name means?
