At first glance, “Jiro Dreams of Sushi” is a foodie’s dream. A documentary made by David Gelb, it tells the story of 85 year-old Jiro Ono, generally considered to be one of the best, if not the best sushi chef in the world. The Japanese government has designated him as a Living National Treasure. His small, unassuming restaurant located in a Tokyo subway station with only 10 seats has become the first restaurant of its kind to be awarded a prestigious three-star Michelin Guide rating. Sushi lovers from around the world go there, calling months in advance and shelling out top dollar for a coveted seat at Jiro’s sushi bar.
