The Old Town Hall is a historic former municipal building at 90 Post Road East in Westport, Connecticut. Built in 1908 as the town's first purpose-built municipal office building, it is unusual architecturally for using cobblestones within a design that is, overall, Classical Revival in style. In 1979 Westport moved its municipal offices to a rehabilitated grade school building at 110 Myrtle Avenue, Westport, CT 06880. The building is currently occupied by Don Memo, a Mexican restaurant. The building was listed on the National Register of Historic Places in 1982.
