On Halloween, October 31, show up in costume and Chipotle will “treat” you to one of its notoriously large “booritos,” bowls, salads or order of tacos for only $3. The bargain burrito (or other menu item) is available from 3 p.m. to closing, so you still have plenty of time to go trick-or-treating or get to a party. We imagine there are going to be lots of “ghosts” converging there on Halloween night to fill their empty bellies. (Get it? Empty bellies! Maybe we’re not as funny as we think.) And be sure to check out our Halloween Happening on the Cheap list for the spooky goings-on in the area. BOO!
