“Tokyo boasts similar food theme parks devoted to ramen, gyōza, ice cream, and desserts. If you don't like takoyaki, you're not entirely out of luck: the stand we visited, Aizuya, also offers radioyaki.

Konnyaku is a noncaloric gelatin made from the root of a plant closely related to the stinking corpseflower.” ThemesTakoyakiKonnyaku Book:Pretty Good Number One: An American Family Eats Tokyo Source: Pretty Good Number One: An American Family Eats Tokyo
