Sunday afternoon at Battery Park Book Exchange is already a solid vibe with the books and bubbly, and adding live music at 3pm makes it an easy yes. Good way to ease into the evening or just post up for the rest of the day. Since this is a working bar with two floors of browsing space, anyone under 10 needs constant supervision while you're sipping champagne among the stacks. The spot goes 21+ on weekends according to some regulars, so if you're bringing younger folks aim for a Thursday show when the door policy loosens up and families can still claim one of those leather chairs before the room fills.
