What is the Russians style of food service?

a service that is related with carvery operations. the food is presented to the host for approval. once approved the food is portioned over the carving trolley and is dumped over the table so that the guests can have the food themselves. the difference between gueridon and Russian service is that it has only carvery operations involved with it but not the flambeing and other gueridon operations and the food is not plated on the trolley for every guest but is presented as a portion and dumped as in English service
