Sunday afternoon at Battery Park Book Exchange is already a solid vibe with the books and champagne situation. Parker's Back at 3pm makes it an easy yes for winding down the weekend without committing to a late night. The champagne and wine selection here is what you come for, beer takes a backseat at this Grove Arcade spot where you're sinking into leather chairs with a glass of bubbly while live music fills two floors of browsable books. Shows run Thursday through Sunday with no reservations, so get there early if you want the good couch spots.
