The C'est Bon opened in May 1966 and for a while was Park City's only hotel. It was sold in September 1978 to the Sweetwater group, who turned the building into condominiums, later expanding with additions to the sides and back.
The complex is Sweetwater Lift Lodge Resort today, with the renovated C'est Bon portion taking up the Empire Avenue façade.
From a vintage postcard:
"The C'est Bon Hotel and Convention Center, nestled at the foot of Treasure Mountains, in the picturesque old mining town of Park City, Utah. Offering the finest in hospitality and superb service. Featuring the Outrigger Lounge and Beach Boy Restaurant, which are must stops on your skiing or summer vacation."
It appears their restaurant did change over the years. For a time it was "The Mandarin".
Among other entertainments, they also had exotic dancers. The best known was Shirley Price, known as “The Duchess”, who arrived in Park City in the 1960s after leaving Hawaii and Las Vegas, and made the town her home and stage. She performed her illustrious act at the C’est Bon and the Ore Haus (which stood at 1410 Empire Avenue). She was so popular that famous actors, especially Chuck Connors from the TV series “The Rifleman”, and children’s book author Shel Silverstein, came to Park City just to see her dance.
