With the rollout of new, preservative-free tortillas last week, Chipotle declared itself the only national restaurant chain that doesn't use added colors, flavors, or preservatives in any of its food. Now, the the burrito purveyor is hammering that message home with a game that'll reward you with a free order of chips and guacamole if you can spot the hidden artificial ingredient on its website.
The game is aptly called "Spot the Imposter," and it's super easy. All you have to do is visit Chipotle's Real Ingredients page and search through the visual list of 51 additive-free ingredients to spot hidden industrial preservatives, artificial colors and flavors, gluten, and gums often used in fast food menu items. Once you find -- and click on -- the hidden additive, Chipotle will send you a mobile coupon via text message for a free order of chips and guac with the purchase of any entree. The deal is good through April 30.
