Manage Food Service Staff. Food and beverage managers are often responsible for recruiting, hiring, training, evaluating and terminating food service staff members. Personnel management of restaurant staff requires experience as well as interpersonal skills.
Those who manage their own business often deal with suppliers and arrange for the delivery of food and beverages and other supplies. Full-service restaurants (those with table service) may have a management team that includes a general manager, one or more assistant managers, and an executive chef.
