This restaurant themed to the club in Tron:Legacy would be paced in the area currently occupied by pizza port.
Facade -the exterior of the restaurant would look like the tower from the film. The tower would not be as tall as depicted in the movie, but would use forced perspective by using painted shadows and other techniques to create the illusion of it being taller. A lightcycle would e outside for photo ops.
Interior -the inside would look like the interior from the film. Light beams would outline the walls and tables using LEDs. Waiters and waitresses would be dressed as programs and would address guest as programs. Castor would announce various things like park closing time, restaurant closing time, music playing etc. Daft punk AAs dressed in program uniforms would "play" music.
At night the building would light up, illuminating the area around it. A LED path starting from the fountain would also light up at night, leading to the restaurant.
