He is a well-known and brilliant chef who wrote the best-selling book Anyone Can Cook and opened the five-star restaurant Gusteau's. His personal motto is that everybody can cook, and he is prone to creating unique recipes. He was the youngest chef in history to open a five-star restaurant and was considered one of the best chefs in the world.
However, after France's top food critic Anton Ego wrote an insulting review (for reasons unknown, as Ego was just one man compared to the masses who adored Gusteau's cooking), the restaurant lost one of its five stars, and the brokenhearted Gusteau died soon after - which, according to tradition, meant the loss of another star. Gusteau's restaurant was passed down to his sous chef Skinner, who was not precisely a follower of his boss's principles. Remy is eventually led to Gusteau's by Gusteau, who serves as his guide.
