Takoyaki is very popular Japanese local casual food (also called b-class food in Japanese) originally developed in the western part of Japan, especially Osaka.

Takoyaki is,

a ball-shaped Japanese snack made of a wheat flour-based batter and cooked in a special takoyaki pan. It is typically filled with minced or diced octopus (tako), tempura scraps (tenkasu), pickled ginger, and green onion.[1][2] Takoyaki are brushed with takoyaki sauce (similar to Worcestershire sauce) and mayonnaise, and then sprinkled with green laver (aonori) and shavings of dried bonito (katsuobushi). There are many variations to the takoyaki recipe, for example, ponzu (soy sauce with dashi and citrus vinegar), goma-dare (sesame-and-vinegar sauce) or vinegared dashi.
