One of my favorite Japanese dish is okonomiyaki お好み焼き. It is like a pancake filled with an egg, cabbage, meat and different sea products (shrimps, calmar, etc.). These pancakes are then covered with a sweet sauce, bonito flakes and seaweed in powder.
There are two kinds of okonomiyaki, those of the Kansai region (Osaka) and those of Hiroshima. The latter is caracterized by the fact it is served on Japanese noodles, yakisoba 焼きそば. During my stay in Hiroshima, I even tried some served on thick noodles called udon うどん.
Hiroshima being famous for its oysters, I also tried okonomiyaki with grilled oysters. It was delicious !
