Change, as the Greek philosophers pointed out, is the only constant. What’s different centuries later is the rapid-fire pace of that change. In “The NRN 50: Game Changers,” we focus on the accelerating forces — the people, ideas, technologies, concepts and trends — currently pushing the envelope and the industry in new directions. This special issue is the latest installation of our NRN 50 series of single-theme issues published each January. This year’s project comes as the industry adapts to a quickly transforming reality in hopes of speeding up a stubborn economic recovery. You won’t want to miss these 50 change makers, from daily deals to McDonald’s executive chef Dan Coudreaut to the iPad, among others, and how they are reconfiguring the restaurant world.
