Head in after 6pm this Halloween dressed as a horrifying processed food product and Chipotle will give you a burrito, bowl, salad, or an order of tacos filled with freshly cooked, naturally raised ingredients for only $2. Then, make sure to snap a photo of yourself to enter the costume contest - one grand prize winner will receive $2,500, with five runners up getting $1,000 each. Twenty runner-runner up winners will receive a burrito party for 20 guests.
