Normal takoyaki, consists of a ball of batter filled with squid, but these takoyaki advertised 10 items including squid, clam, sausage, cabbage, mashed potato, quail egg, mushrooms, corn, and 2 other things I could not identify (sorry). They were also about 3-4 times larger than the usual takoyaki- about 3-4 inches in diameter.
The ball is then topped with okonomiyaki sauce, bonito, and mayo. The cart offered alternate toppings like cheese, kimchee, and onions as well.
It was like eating a giant spherical Japanese hot pocket- yum.
