The movie is called Jiro Dreams of Sushi. My recollection is that Jiro's tiny restaurant was the first Sushi restaurant to receive 3 stars, and it received them in the first year it was visited by reviewers. The movie itself is a stunning testament to the power of doing something narrow and deep extraordinarily well. I cannot recommend it enough.
