In the words of the great Anthony Bourdain....
Chef: "I think I earned that title, but my definition for chef is just a cook that leads other cooks, who worked as a chef. Chef isn't a name that means you're the best cook, or run a great restaurant. A chef is anybody who can walk into a professional kitchen, effectively serve the customers who come in the door, and somehow manage a staff and get them to do what you want and execute your plan."
So his title now? "Ex-cook-who-tells-stories. I kind of like that one.
