Preparing okonomiyaki takes a lot of concentration. This is a popular Japanese dish that looks like an omelet or a pancake and is made with ingredients such as flour, egg, potato, cheese, onions, cabbage, and other vegetables. But really you can put anything you want in it. It is then grilled to your taste and you can season it with mayonnaise or seaweed flakes. Some restaurants, like this one, offer the DIY (do-it-yourself) option. Its a lot of fun and a good way to spend time with friends. Definitely a must on your next visit to Japan or even in the Little Tokyo neighbourhood of your city!
