We were in Japantown the other day and walked by one of the many restaurants. Nick reminded me of the time he commented, "Wow, they have to make that food everyday and put it in the window....seems like a waste." To which I replied, "you know it's plastic, right?"
Anyways, this is very common in Japanese restaurants. And apparently we were the cause - and by "we", I mean Americans. After we bombed the heck out of Japan back in WWII, us and the Europeans decided we should probably help them rebuild (how nice....). When "we" arrived there, we couldn't read the menus. So the Japanese restaurant owners had wax models made to show Americans what was on the menu. That way the Americans could pick the food based on what it looked like.
Now, it has become a HUGE industry. Restaurants have been known to custom order an entire window display - upwards of 1 million yen ($10k). I actually had a mini set of sushi when I was little. It was fun to play with. I kinda wish I still had it, it would make for some fun magnets.
