Early planning submissions and recent "space" themed suggestions one could only assume it would be a Food Loop (as food flies around) but probably not titled that. I believe the restaurant signage will be Galactica which they trademarked but the ride together will become known as Air: Galactica as others suggested.
Someone over at TS did mention about maybe a possible sponsor by Mars, would make sense if its space themed. (Galaxy, Mars, Milky Way) You could have the food flying around planets as if its going around its orbit etc..
A new theming turret will be installed on the roof of the building.
If its space themed I'd imagine it'll be like a gun turret, the building is the spacecraft & you fly out of the ship and on a mission.
