Kodomo No Nomimono Children's Beer
Yep - you read that right: children's beer. I was merely looking to taste something new at Nirai-Kanai when I figured I'd give this stuff a try. It literally translated into "children's drink," so I wasn't expecting it to come out in a beer bottle, be served in a little Japanese beer glass, and come complete with some head on top.
It tasted like apple soda, but the idea of positioning faux-beer toward kids was a bit disturbing. (I suppose that one could also bundle it with some of those candy cigarettes to extend this bizarre concept.) Only afterwards did I realize that I had seen this before: at a toy store in Tokyo. Well, as least now I got to try it...and sadly, it was tasty enough that I'd get it again.
