One thing I can enjoy most after moving to Japan was okonomiyaki. And it was very cheap! Although it depends on where you choose to go, one mixed bowl of okonomiyaki usually costs around 5-6 bucks in Japan. Thanks to this reasonable price, I could enjoy several menus and flavors whenever I ate out for okonomiyaki. Finding Japanese restaurants where serves good quality okonomiyaki was very hard in my home country and it basically was extremely expensive. I visited several restaurants; however, they served me fully-cooked okonomiyaki. But yes, a lot of okonomiyaki restaurants in Japan adopts Do-It-Yourself system so that you can make yours by your hand.
