I think the interesting thing here is the tech development angle; online / mobile ordering and delivery service. I'm sure that it's agreed at Sequoia that the restaurant chain idea is just a hard testing ground for the technology.
The tech is what will be worth the money; the rest of this is just sort of the press being slow.
That said, I do really like the idea of a mobile-integrated ordering and delivery system for the restaurant industry, and of course, fast-concept food is the right place to test it.
