When Michelin was fairly new to Tokyo, a critic wrote a guide to the "Famous restaurants that you should avoid at all costs, and unknown restaurants that you must go to." The premise of the book was that it's better to seek out hidden gems, which Tokyo has in abundance, than to pay top dollar at celebrated restaurants that are resting on their laurels. Unfortunately, it hasn't been updated since 2009, but I think the premise stands - Although some famous restaurants offer better value than others, "best value" and "most famous" are somewhat contradictory.
