Elementary school student Eric Theodore Cartman described his experience at Casa Bonita as “totally” worth making an entire town panic, losing all his friends and going to juvenile hall for a week in an episode of the TV show “South Park.” For more than four decades, Casa Bonita, located in Denver, has been an iconic Colorado “eatertainment” establishment offering dining and entertainment, including cliff-diving shows, live music and an amusement arcade. Now stricken by bankruptcy and its future uncertain, Casa Bonita could very well find a home with the creators of “South Park.”
