Kids Eat Free at Chili’s? Yes, you heard me right! I’m sure you like free. Who doesn’t. We love taking the kids out to eat on the "Kids Eat Free" days. For the past three years, Chili’s has maintained the tradition of offering a Kids Eat Free promotion on Halloween. All you have to do is bring in your little princess or prince (… or whatever else they have decided on) any time from Oct. 29-31 to take advantage of this offer.
