Takoyaki (たこ焼き) is a very casual fast food in Japan. It might not be easily found at Japanese restaurants in the US or other parts of world even though it is a very popular dish.  Takoyaki tastes a little bit like round shaped Okonomiyaki, but it has a much different flavor from the Tako (octopus) cooked inside them. In most parts of Japan, people don’t treat Takoyaki as a meal.  Many people typically think of Takoyaki as something you get from street vendors at festivals and events.
