Canter's Deli has a special performance space known as the "Kibitz Room"; there, every Sunday night from 10 p.m. to 11:30 p.m, singers can belt out a couple of songs in the room where, on other late nights (go there around 2 a.m.) people like Sting and Mick Jagger have been known to step up to that same mic. You'll find cocktails and a convivial atmosphere at this open-all-day-and-night deli; they've been pulling people in at all hours since 1931. The Kibitz Room is only open until 2 a.m., however; but that's been late enough for it to have evolved into a legendary place for jam sessions with world-class musicians.
