What is the name of the maître d' at Gusteau's?

The maître d’ at Gusteau’s is named Mustafa. In Ratatouille, Mustafa is the restaurant’s chef de salle, a front-of-house position responsible for overseeing the dining room and helping manage service.

The character is voiced by John Ratzenberger, a longtime Pixar voice actor whose recurring appearances became a studio tradition. Mustafa is seen among the staff at Gusteau’s, the Paris restaurant founded by the late chef Auguste Gusteau. His role places him on the service side of the restaurant rather than in the kitchen brigade.

Viewers can easily confuse Mustafa with the other named employees. Skinner is the restaurant’s short-tempered head chef and manager, Horst is one of the cooks, and Larousse is another kitchen worker. Mustafa’s title also explains why he is associated with greeting, seating, and supervising guests rather than preparing the dishes Remy secretly helps create.
