I usually find okonomiyaki to be good while eating, but I tend to feel gross afterwards. I'm sure it's more to do with the dough and the mayo on top. I don't care much for okonomiyaki too much. We used to make it at home, pretty much just throw on whatever you want. In the end it was pretty much all to do with the sauce, or Bulldog sauce

Takoyaki's only good when they're fresh. The local Japanese food store has them, but they're cold, and it just doesn't taste the same. Kind of like fries - fresh is best. The Japanese festival does a good job of it, at the very least they're fresh so they're good. And really, you just can't go wrong with Bulldog sauce!
