I don’t believe in free will, not really, and one of the reasons why is lunch. I go to a build-your-own-whatever place, I contemplate the nearly infinite combinations of ingredients, I wind up ordering the same damn thing.

Ells has secretly been working on a vegan, robot-centric new restaurant concept and in recent weeks has shared lots of details about it with Elizabeth G. Dunn — a gifted food writer who would never order as boringly as I do. If you want a preview of the future of lunch, put down your sad desk salad and read.
