Chipotle Mexican Grill, Inc. announced Tuesday a promotion taking place every Sunday during the month of September.

Every Sunday during the month of September, customers at Chipotle Mexican Grill will receive a free kid’s meal with the purchase of an entrée. To accompany each kid’s meal, Chipotle has also partnered with the beloved children’s book Dragons Love Tacos by Adam Rubin and illustrated by Daniel Salmieri to create limited edition in-store activity sheets.

“For more than two decades we have been serving families better food made with ingredients parents can trust—ingredients raised with respect for the land, the animals, and the farmers who produce them,” says Chris Arnold, communications director at Chipotle. “We think good food is at its best enjoyed with good company, and we hope families will join us on Sundays to share a meal together.”

The kid’s meal promotion is valid when purchasing a burrito, bowl, salad or order of tacos, and includes any Chipotle kid’s meal, including the build-your-own option and the quesadilla. Transactions that include the free kid’s meal will count towards Chiptopia, Chipotle’s loyalty program that rewards customers who make multiple paid visits to Chipotle each month with free food when transactions total at least $6. The promotion is available every Sunday in September.
