On our humble opinion the KitKat isn't the king of wafery biscuits. It's younger brother KitKat Pop Chocs owns that crown.
In Japan they still prefer the original two finger classic and University of Tokyo students have made a giant version, measuring 100 x 60 x 20cm and weighing 80kg. It's part of a push to encourage high school students to prepare for the forthcoming entrance examinations in Tokyo.
KitKat is considered a lucky food in Japan as it is pronounced "kitto katsu" in Japanese which means "I surely win".
