I'm a regular at Chipotle, the casual dining Mexican restaurant chain, owned quite clandestinely by McDonald's. Got my lunch to-go yesterday, and upon finishing, go to throw away the bag and remnants. Some wording on the bottom of the bag caught my eye, and it is the simplest drive to web tagline I've ever seen. Three words, followed by their URL: "Gripes and Happiness. Chipotle.com"

Short and sweet, but speaks volumes, no? With 3 words they let you know they are accessible, and they want to know what their customers think. Fanstastic.
