Portabello, a sprawling Orange County mansion, spans three oceanfront lots and has its own indoor mall. Its reproduction "Main Street" consists of a movie theater, bowling alley, a café and a "Kay's Jewelers" that doubles as a jewelry display room and the entrance to the home's vault. The house also has two saltwater swimming pools with waterslide tunnel, a garage for 12 cars, and many more amenities. There is no record of the Portabello's sale, but the official website is still active.
