'Ganso Butadon-ya TONTON,' inspired by the traditional pork rice bowl from Obihiro, Hokkaido, is known for its signature grilled pork donburi, featuring pork marinated in a secret sweet-and-spicy sauce and grilled twice for a rich, aromatic flavor. The 'Special Don' combines TONTON’s premium grilled pork belly with authentic unagi (grilled eel), creating a high-energy dish perfect for the summer season. Due to popular demand following last year’s success, this fan-favorite menu item returns for a limited time in 2026. The eel used is carefully selected from farms with strict water quality controls. Each eel is meticulously steamed and grilled according to its condition, resulting in a tender, fluffy texture with a rich aroma. The mild soy-based sauce enhances the natural flavors of both the eel and pork, delivering a deeply satisfying and hearty meal. The 'Special Don' offers the best of both worlds: the robust, smoky flavor of TONTON’s grilled pork belly and the luxurious taste of premium eel. It’s the perfect energy booster for beating the summer heat. Experience TONTON’s signature boldness and overwhelming satisfaction.
