If you want to feel like the ultimate jazz insider, drop by Dogpatch Saloon, one of the best live music bars in San Francisco. Dogpatch Saloon on Sunday at 4pm to witness an impromptu jazz jam with local musicians. The place is a tiny dive on the wrong side of Potrero Hill-all the more surprising when you settle into a booth and start soaking in the musical genius. A fiver opens the door to cocktails, four hours of live jazz, and free snacks and chili. You can get your fill and still have time for a Sunday night dinner somewhere glam. If you are in the mood for live jazz other nights of the week, it is worth calling, as Dogpatch Saloon often have something of interest on stage.
