Taco Yaki is grilled squid balls that's usually being sold by street vendors in Tokyo. At least that's how I remember them. I didn't see it on the menu in Temari. Does any one know if this is being served anywhere in the metro area?
I know Tako-yaki is sold at a Japanese resturant called Blue Ocean (Fairfax, VA in Fair City Mall) that I frequently go to. I can't say its the best (compared to the streets of Osaka where it originated!) but its pretty good.
