We had burritos today in the office...ordered them online from www.chipotle.com. I was really impressed with the Chipotle ordering system. It allows you to see a picture of the trimmings (i.e. cheese, sour cream, black beans vs. pinto beans, etc.) while it asks you (audibly) to pick what you want. They really did a nice job technically and logistically...they went a long way in terms of thinking through the customization and order pick-up process. Very nice work!
