Takoyaki is a Japanese fried or grilled dumpling usually filled with octopus. Watching Fresh Street use their special grill pans is fascinating and intimidating. But the flavors and the different fillings that they offer are anything but intimidating.: kimchi (my favorite), sweet corn, mozzarella, short ribs, octopus, scallops...
Get thee some (but save me some kimchi).
