Eighty-five-year-old Jiro Ono, considered the world’s greatest sushi chef, is the proprietor of Sukiyabashi Jiro, a 10-seat restaurant inauspiciously located in a Tokyo subway station. Despite its humble appearance, it is the first restaurant of its kind to be awarded a three-star Michelin Guide rating, and sushi lovers from around the globe make pilgrimages. “Jiro Dreams of Sushi” is a thoughtful and elegant meditation on work, family and the art of perfection.
