Japan has to have the coolest Burger King. I mean, I know they installed those luxurious sound booths, but I think this giant burger definitely takes the cake. BK Japan has announced that they will be selling a 22 cm (or 8.6 inch) burger that will come in two flavors — avocado and cheese nacho. It’s conceptually like pizza where you cut the mega burger up into slices to serve. Apparently, this pizza-size burger costs $21.50 each and will only be available from Dec. 8 to 25. I think I’m going to try one when I’m back in Japan!
