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.
Today, these same managers are responsible for bringing many of the vegetarian options that restaurant goers see on their menus. The challenging part of the food and beverage manager position is to adjust menus in such ways that new items can be produced within budgetary constraints while they attract sales. Food and beverage managers may opt to roll out pilot programs for new food items to ensure that these new additions maximize restaurant revenues as expected.
