Café-chantant
Café chantant (French: lit. “Singing café”) is a type of musical establishment associated with the belle époque in France. Although there is much overlap of definition with cabaret, music hall, vaudeville, etc. the café chantant was originally an outdoor café where small groups of performers performed popular music for the public. The music was generally lighthearted, sometimes risqué, even bawdy but, as opposed to the cabaret tradition, not particularly political or confrontational.
