Triclinium

A triclinium (plural: triclinia) is a formal dining room in a Roman building. The word is adopted from the Greek τρικλίνιον, triklinion, from τρι-, tri-, "three", and κλίνη, klinē, a sort of "couch" or rather chaise longue. Each couch was wide enough to accommodate three diners who reclined on their left side on cushions while some household slaves served multiple courses rushed out of the culina, or kitchen, and others entertained guests with music, song, or dance.
