The 85-year-old Jiro Ono is considered by many to be the world's greatest sushi chef. He is the proprietor of a 10-seat sushi-only restaurant inauspiciously located in a Tokyo subway station. Despite its humble appearances, it is the first restaurant of its kind to be awarded a prestigious 3-star Michelin review, and sushi lovers from around the globe make repeated pilgrimages, calling months in advance and shelling out top dollar for a coveted seat at Jiro's sushi bar.
