Service à la française is the practice of serving various dishes of a meal at the same time, with the diners helping themselves from the serving dishes. That contrasts to service à la russe in which dishes are brought to the table sequentially and served individually, portioned by servants.

The historical form of service à la russe is a manner of dining with courses brought to the table sequentially, and the food portioned on individual plates by the waiter.
