The ``Ginza Series'' conveys the good old Western food culture of Ginza. The medium-spicy version is based on a fragrant two-stage bouillon, and the flavor of thinly sliced ​​beef is brought out by sautéed onions and butter. The deep flavor that goes well with freshly cooked rice is truly a ``luxury dish''. It takes a lot of time and effort to make something delicious that will make everyone smile.
