Was it Japan that did the theme restaurant based on the NAZI Concentration Camps, complete with Swastika flags?
I’m pretty sure it was an Asian country. There was enough of an outcry that the owner closed it down.
The U.S. isn’t much better. There was an S&M/Bondage themed restaurant in New York. I don’t know if it’s still open.
That was in South Korea (Pusan), as well as one briefly called “Hitler” was in Bombay, Korea, too (but it shut down).
