I think a trip to Tokyo should be on my to do list this year. Gourmet KitKat store?
Japan is famous for their Kit Kats and apparently the country has some unique KitKat flavors that aren't available elsewhere. Just a few days ago, they got the first Kit Kat specialty store on earth. Called the KitKat Chocolatory, this place offers gourmet KitKats and that's it.
There are three flavors currently: the "Sublime Bitter," which is made with couverture, "Special Cherry Blossom Green Tea," which uses extract powder from cherry blossoms, and "Special Chili," which has a chili pepper cream between the wafers.
