I made Hiroshima-style Okonomiyaki a couple months ago. And then a million times over since then. We are crazy for Okonomiyaki! It is not quite like anything I've ever eaten or cooked before. Familiar flavors, such as the savory pancake and noodles mix with the smokey katsuobushi (bonito fish flakes) and Okonomi sauce which were new to me! I highly recommend heading here for a step-by-step guide to Okonomiyaki. Or you can find the (I think more common?) Osaka style here.
