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.
A restaurant manager is someone who is the 'face' of a restaurant and whose main responsibilities are to deal with customer service issues as well as to ensure that the food quality coming out of the kitchen is the best it can be. He or she also deals with any staffing issues and ensures that everything runs as smoothly and profitably as possible.
