Ada's new restaurant was called Cafe Paradise and was featured on AW from 1989 to 1993. This restaurant was phased out around the time that Constance Ford's Ada died. Ada hired her old high school boyfriend from World War II, Sidney Sugarman, to work at her restaurant as a chef. Sidney was played by Larry Haines who had previously played Stu Bergman on Search for Tomorrow for 35 years. Sidney was featured on the show until the Summer of 1989.
