At Kawagoe Festival in Saitama, we stopped by a chocolate banana vendor.
Chocolate bananas, along with candied apples, takoyaki and whatnot are a typical festival snack in Japan. This booth in particular was interesting because they have a special deal.
When you buy one chocolate banana for 200 yen, you get a chance to challenge the shop keeper in a game of paper scissors rock! If you win, you get two bananas for the price of one!
If you lose, you just get your one banana.
