Rather than dressing up as a Chipotle food item on Halloween for a free burrito, this year, customers who visit a Chipotle restaurant after 6pm on Sunday, October 31, 2010, dressed up as a "horrifying processed food product" can get a burrito, bowl, salad, or an order of tacos (basically any entree on the menu) for $2.
While you're picking up your $2 burrito, you can snap a picture of it inside Chipotle to enter their online costume contest (details here) with prizes up to $2,500.
Proceeds from the event will be donated to Jamie Oliver's Food Revolution (up to $1,000,000).
You can check out the video promoting their message and event, featuring celebrity chef Jamie Oliver below:
