Who is the matrade' on hells kitchen?

The term "matrade" seems to be a typo or misinterpretation. If you meant "maître d'," this refers to the head waiter in a restaurant, responsible for managing the dining room and ensuring smooth service. In "Hell's Kitchen," the maître d' typically oversees the front-of-house operations, interacting with diners and coordinating with the kitchen staff. In the show, the role is often portrayed by a character like James or other staff who assist Chef Gordon Ramsay.
