'酒吧' (jiǔ bā) is a compound noun meaning 'bar'—a social venue where alcoholic drinks are served, often with music, casual seating, and a relaxed atmosphere. The first character, 酒 (jiǔ), means 'alcohol' or 'liquor', reflecting the primary product served; the second, 吧 (bā), is a phonetic loanword from English 'bar', adapted into Chinese with the same pronunciation and function. Together, they form a widely understood, modern term used across mainland China, Taiwan, and other Mandarin-speaking regions.

This word is neutral in register—neither formal nor slang—and appears frequently in daily conversation, advertisements, maps, and travel guides. It's distinct from more traditional drinking establishments like 酒馆 (jiǔ guǎn, 'wine house') or 酒店 (jiǔ diàn, which usually means 'hotel', not 'wine shop'). '酒吧' implies a Western-influenced, urban setting, though many local bars blend Chinese and international elements in decor or menu.
