Burgers are just an example of 1 food item that's versatile enough you could dress it up or play with it. It's not all about burgers. It's about having a themed menu that fits the surroundings. There's plenty of chefs out there (known, less-known, and unknown) who could do some amazing things to bring cohesion between the setting and what's on the tables, give us some mind-blowing food, AND make the experience of the Sci-Fi Dine-In completely immersive on all levels. That's the point.
The menu as-is is dull and has nothing to do with a drive-in. It's uninteresting and is a stark contrast to the theme of the restaurant. That's the point. Not --Hey, we need another burger--.
This.
