In 1982, the company (including Taco Bueno fast food restaurants) was sold to Unigate (now Uniq plc). In 1992, Unigate sold the restaurants to CKE Restaurants, owners of Carl's Jr. In 1997, the two remaining Casa Bonita restaurants were spun off by CKE as part of Star Buffet. The Tulsa location closed in September 2005, then reopened for a 2-year run under the name Casa Viva, and went out of business in December 2007. Casa Bonita was reopened by Star Buffet under the original name in late July 2008. In March 2015, It was announced that the Lakewood Historical Society decided to make the restaurant a historic landmark of the city.
