Slightly gritty, hole-in-the-wall Agent Gallery Chicago makes for a fun adventure. A School of the Art Institute grad and former manager at Salvage One, Mariano Chavez brings an artsy sensibility to the industrial pieces he finds for his Wicker Park shop—be they old marquee letters or vintage science-class posters. If you prefer a more pristine shopping experience, we recommend previewing his eclectic finds online. 916 N. Damen Ave., 312-498-6818, agentgallerychicago.com
