Restaurants: He cooks at the French restaurant, La Rochelle (the restaurant's website), which offers a great view of Tokyo from its 32nd floor location. The restaurant's name is from a city in France where Sakai spent some time (as revealed in the France Showdown special).
Background: Sakai is known as a lady killer in Japan and he is often called the "Delacroix of French cuisine" because of the beautiful way in which his dishes are presented. Sakai is a member of the Club des Trente, an organization of French chefs in Japan (there is another group of younger chefs, Club Mistral, who have been on the show and challenged Sakai a few times). The Club des Trente also has, in its membership, retired French Iron Chef Ishinabe and many of the French chefs who have been challengers on Iron Chef are also members, including Jo Etsuo (Battle Wine).
