【简答题】
Restaurant services There are mainly five kinds of restaurant services. They are gueridon service, silver service, plate service, buffet (self-catering) service and takeaway service. The first three kinds of services are sit-down services and a buffet service can be both a sit-down one and a stand-up one. Take away service is usually associated with snack bars and fast food outlets. In gueridon service, the waiter must always be well-trained and skilled for he has to perform such things as filleting,carving and cooking special dishes in front of the guest.In silver service,the food is prepared in the kitchen and brought to the guest’s table on a silver tray. In plate service, the waiter takes the plated meal from the service hotplate and then put the plate on the guest’s table. All that he has to do is to make sure that the correct lid is laid and the necessary accompaniments are available on the table. In buffet service,a guest picks his or her own tray and cutlery from one end of the service table and chooses whatever dish he or she 1ikes. Two forms of meals are distinguished:a la carte and table d’hote. An a la carte meal is ordered course by course from a menu where each item has a separate price while a table d’hote meal has a fixed price for a complete meal or several courses.
