The chef devotes himself to good health through a balanced diet, using Chinese medicines as seasoning to serve food that is salutary for both mind and body. Vegetables from his native Oita are grown by natural methods, making them gentle to the constitution. At dinner, there is a wide range of à la carte dishes, leaning toward Sichuan and Shanghai influences. The chef allows himself an individual take with the mapo tofu: drawing on a wealth of experience, he offers a choice of Sichuan, aged doubanjiang (Chinese broad bean chili paste) and salt. Lunchtime set menus are also popular.
