Chefs and dinner cooks prepare meals in restaurants, hotels, and institutions. Although the terms "chef" and "cook" are used interchangeably, chefs tend to be more highly skilled and better trained. Many chefs have earned fame for themselves and their restaurants by their skillful preparation of dishes. The specific duties of chefs and cooks often are determined by the restaurant in which they work. Institutional chefs and cooks prepare large quantities of a limited number of menu items. Restaurant chefs and cooks typically prepare a wider selection of dishes and usually cook most orders individually.
