The Michelin stars are judged by a group of selected "gourmet spies", who are called "inspectors".

Every time inspectors go to a restaurant or hotel to judge, they need to hide their identities and sneak into the accommodation and review. The scoring items they need to refer to include the restaurant's food (60%), dining environment (20%), service (10%) and wine pairing (10%).
