This building has been extensively remodeled recently when the New Orleans style 2-story gallery was added. It was the last building on the Square to be renovated. Built sometime in the late 1880s, the building housed Henry McDougall's Buckhorn Saloon from around 1900 until 1905. After McDougall's death, his wife added the second story, running a combination rooming house, office building, and saloon.

William A. Zesch obtained the building from Mrs. McDougall, his sister, and operated a meat market and grocery store with Harold Zesch and A.W. (Bert) Zesch. They had to close during the Depression because customers could not pay their accounts. The building still contains a well and pump that once supplied water for the entire block. The well room also has a barbecue pit dating from the time of the meat market. Mason Square Bed & Breakfast on the second floor offers comfortable rooms, each with lovely antiques and a private bath.
