The interior of the restaurant was designed by Ed Sotto and Ellen Guevara for Walt Disney Imagineering (WDI). WDI designer Michael Valentino created the interior of the building and exterior lighting program. (WDI is the master planning, creative development, design, engineering, production management, and research and development subsidiary of the Walt Disney Company.)
The Theme Building was part of an overall $50-million “Los Angeles Jet Age Terminal Construction” project, which began in 1960. The building itself was completed in August 1961 at a cost of $2.2 million. On December 18, 1992, the Los Angeles City Council designated the Theme Building a City Cultural and Historical Monument.
