A bar or tavern serving alcoholic drinks, especially in the Old West; also a large reception room on a ship.
From French 'salon,' from Italian 'salone' meaning 'large hall.' Originally referred to fancy reception rooms, but in American frontier usage came to mean a bar.
The word 'saloon' shows how the same root word traveled through languages (French to Italian to English) but completely changed meaning based on American frontier culture and geography.
