Takoyaki
"Tako" is the Japanese word for octopus, pronounced exactly like Mexico's "taco". Octopus is a treat to the Japanese, and they have one snack in particular called takoyaki , which kind of means something like octopus from the grill.The meat isn't really grilled, more like set inside a ball of batter which is then cooked as you see above. The batter doesn't truly set the way most of ours would, so the finished product emerges kind of gooey and would stick to your fingers if you didn't use the toothpicks they provide. Inside the batter lies a tender piece of octopus abnd the whole thing is topped with a kind of citrus sauce, almost like a ketchup, then with a bit of Japanese mayonaise. Eaten as a snack rather than a meal, you might find this available late at night after you leave the pachinko parlors.
Takoyaki isn't that expensive, about Y500 or $4.50. I imagine the price varies with location.

A great view, best with a cold bottle of white
