Having arrived on Clark Street in 2002, Charlie’s Ale House is as much a fixture of Andersonville as anything else on the strip. But “everything has a shelf life,” Marty Fosse, co-owner of Charlie’s, says. And so this week Fosse and his business partners are unveiling a new concept in the Charlie’s space: Acre, a pub with two identities. In the first identity, the “Tap Room,” chef Carlos Ysaguirre (also the chef at Anteprima, which Fosse and his partners also own) goes casual, putting out Asian-rubbed brisket sandwiches and wild boar chili. In the dining room side, Ysaguirre will put out mostly upscale seasonal American fare (like the chocolate cake with pawpaw ice cream, pictured) . Still, fans of Charlie’s shouldn’t worry too much—on both sides of the restaurant, the beverage program focuses on beer. 5308 N Clark St (773-751-0140).
