Every festival, every single one, comes with food stalls. Some are good, some are not so good. But most of them are cheap. And there's always, always, たこやき (takoyaki, octopus dough balls) as seen on the right side here. And in this case also すいとん (suiton, sweet potato on broth) as seen on the left side here.
