Downtown's Art Walk has become an institution for roving hipster aesthetes, curious warehouse-dwellers and food-truck aficionados. The work? It's hit-and-miss, but you can't argue with the one weekend a month when the Old Bank District sees Cairo-level street traffic of bright young things spilling out of tiny galleries and progressive museums in their angled-haircut finery. Downtown L.A., noon-9 p.m. Thu. www.downtown artwalk.com.
