Sunday late afternoon at 5 Walnut feels right for this, the kind of low-key wine bar situation where you can settle in without committing your whole evening. Four o'clock start means you're out before dinner or staying through it if the vibe's working. This downtown Walnut Street spot holds maybe 75 people on a good night, so you're basically sharing a living room with whoever's playing. Seating fills fast and those window bar perches go first, but that's the whole point, grab a glass and a cheese board from the shop next door and settle in close.
