This iPhone/iPad/Android/Blackberry app is presumably an April Fool’s thing. But would it be wildly out of character if Steven Spielberg were to endorse a chain of this type? He’s been involved in theme-park promotions and TV spinoffs based on his films. It wouldn’t be much of a stretch. No Schindler’s List chili fries, of course, and probably no Lincoln dogs, but this kind of thing would be right up his alley.
