Kozy Okonomi-yaki Teppan-yaki is a Japanese teppanyaki izakaya on the 9th floor of Cityplaza in Causeway Bay, Hong Kong. The okonomiyaki is neither too sweet nor heavy, and steak and large seafood are grilled on the teppan in front of you. Reservations are required to sit at the teppan counter and watch the chef cook, and the restaurant stays open until around midnight. Ventilation is weak, so clothes pick up the smell of teppanyaki after a meal.
