Boasting a sophisticated retro-speak-easy vibe, the Jazz Standard is one of the city’s largest jazz clubs, with well-spaced tables seating 150. The rule is straightforward, mainstream jazz by new and established musicians, including amazing artists and the occasional big name like Branford Marsalis.  A limited menu from Danny Meyer’s barbecue joint, Blue Smoke, upstairs, is available. Jazz, blues, and barbecue—hard to go wrong with that.
