The McDonald's in Durham, NC had this years ago. It didn't work so well. Too many choices, too many screens, and let's be honest, despite being around a hi-tech research area, most of the clientele were blue collar types who just wanted cheap food fast. A lot of people tried them, but after a couple months they just weren't being used and they got packed up. If there is some incentive to use them, people will. Like discount, or the regular line is long. Forcing people to use it will just piss people off. Good luck to them. But there is a reason they don't sell Rolex at Wal-Mart and Dollar General. Know your customer!
