Okonomiyaki is a savory Japanese pancake that is made with a batter of flour, grated yam, eggs, and shredded cabbage. It is then topped with various ingredients such as sliced pork, seafood, and vegetables, and cooked on a griddle. In Tokyo, you can find okonomiyaki restaurants where you can either cook the pancake yourself on a tabletop grill or have it prepared by the chef. Okonomiyaki is often served with a special sauce, mayonnaise, and bonito flakes.
