Jiro Dreams of Sushi is a great documentary! I had relatives visiting from California and eating a Jiro's restaurant (or his son's) was their top priority. However, due to the price and the "unknown" of what would be served, they opted for something more affordable yet still Michelin-starred. I recommend lunch at Sushi Iwa located in Ginza, Tokyo. For 8,000yen per person for a 13-course meal, the sushi was phenomenal and the ambiance a bit more relaxed. Master Chef Iwa was really great with his technique and explained a few things when we looked confused.
I've only seen this video where a guy filmed his visit to Jiro's restaurant and he says it was great https://www.youtube.com/watch?v=TRAmdcnur1A
But then in the comment someone says it it his son's restaurant.
And here is the opinion of Andy Hayler, a food critic at Elite Traveler who has dined at every 3-star Michelin restaurant in the world: http://www.businessinsider.com/is-sukiyabashi-jiro-actually-worth-it-2014-4#ixzz3aMZm1W7G
