Haven't figured out your Halloween costume yet? Well, not to try to sway you, but if you dress up as a burrito or anything burrito-related, probably involving foil, you can get a free burrito at Chipotle on Halloween after 6 pm. Actually, you can also get free tacos, a bowl, or a salad, not just a burrito. So dress as the Mexican fast-food ingredient of your choice and get free dinner! What other costume can promise you that?
