Another L.A. institution has been sold. Du-par's coffee shops, which began in 1938 at the Farmers Market, were purchased by the family that used to run the Tiny Naylor's restaurants. A Times website story says the Du-par's at Farmers Market will close for 60 days of renovation then reopen under the same name. The Studio City and Thousand Oaks locations will close briefly in August for remodeling.
