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.
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. Address Customer Concerns. One of the primary ways that food and beverage managers meet their sales and revenue goals is through excellent customer service. Great service sets the ambiance of restaurants, and it makes guests want to repeat the experience.
