【简答题】
 Regardless of whether a server has previous restaurant experience, he will need to go through training when hired at a new restaurant. Servers need time to become familiarized with the new restaurant's practices, customers and menu to do their job efficiently. Developing a thorough food-server training program is essential to restaurant's success. One of the first things new servers should be taught is the restaurant's concept. For example, if a restaurant serves affordable seafood in a family-friendly setting, servers will need to keep this in mind so that they can better understand the restaurant's target customers. Other basic information that servers should know include how long the restaurant has been in operation, the name of the founder and any special or interesting facts about the establishment. Knowing the layout of a restaurant is extremely important for a new server. She needs to know where restrooms, emergency exits, kitchens, dining areas and storage rooms are located to do her jobs efficiently. A server needs to have a thorough knowledge of a restaurant's menu. Customers will ask for recommendations, and they'll inquire about house specialties and nutritional information. If your restaurant has an extensive drink menu, knowing drink details is vital as well: Customers will often ask what drinks go bets with certain dishes. If a server is able to taste server dishes during training, he will be more knowledgeable about giving customers personal recommendations.
