I recall reading just so-so things about Mifune Don in Miyako Mall and have avoided, but since the Nijiya market in Japantown has been out of Okonomaki the past two times I've been, I needed a fix.
They had several meat and seafood combination options on the menu, but I just wanted ika (squid) and my server accomodated. I was sitting where I could see into the kitchen and noted the cook was not Japanese, which worried me, but I was pleased with my okonomiyaki.
I've only had freshly made from Otafuku in the East Village, NYC. Mifune Don's was comparable, and I think worth a try for anyone that's never had it. It's a very basic restaurant, but they had a decent (8+) selection of Sakes by the glass for just $6.00.
For $6.95 it made a nice lunch. I'll go again when I want okonomiyaki made to order, as I believe my options are limited in SF.
There is a restaurant in Lomitas, CA called Gaja Okonimayki that let's you cook your own and next time I'm in Orange County I'm going. I'm truly obsessed with this dish!
