The 'chef business' is insanely competitive and arguments about who is the "best" are so hopelessly subjective that conversations regarding such are ultimately futile if a resolution or even a consensus is sought by the participants.
That said, Joel Robuchon did lead the world in Michelin Stars
- and by a wide margin.
To those who would sniff at that achievement saying that he was "just a good businessmen
" (and worse) I would cite his singular achievement to his being both a master of his craft and
a great teacher.
That is an exceedingly rare combination; therefore, I believe he had a valid claim to have been the
Chef of his generation. Happily, his students carry on.
