Gyo-kaijin encapsulates everything life-affirming about Japan’s dining scene. It is inexpensive, has impeccable service, a lively ambiance and, most of all, a standard of cuisine that you have to eat to believe. It was a serendipitous discovery, but knowing Japan as I do, I recognize that there were probably half a dozen other establishments lurking around the corner that would blow my mind and my tastebuds in a similar fashion.
