Chefs are the most highly skilled and trained of all kitchen workers.
Due to their skillful preparation of traditional dishes and refreshing twists in creating new ones, many chefs have earned fame for both themselves and the establishments where they work. Although the terms chef and cook are still used interchangeably, cooks are less skilled. Large eating places tend to have varied menus and employ kitchen workers who prepare much more of the food they serve from scratch. Executive chefs coordinate the work of the kitchen staff and often direct the preparation of certain foods. They decide the size of servings, sometimes plan menus, and buy food supplies.
