The Chicago Cubs and White Sox battled on the North Side this weekend, and baseball fans will have the chance to score some free food by showing their team pride.

On Sunday afternoon, Cubs and Sox fans who visit any Chipotle location in Illinois or in Northwest Indiana will receive a buy-one-get-one-free offer from the restaurant.

All fans have to do between the hours of 10:45 a.m. and 10 p.m. is show up to a participating restaurant while wearing the color of their favorite team, whether it be Cubbie blue or White Sox black and silver. If they do, they’ll get a buy-one-get-one offer on any burrito, salad, or taco at the restaurant.

The Cubs and White Sox began their three-game series on Friday afternoon at Wrigley Field. They’ll also play later this season at Guaranteed Rate Field in late September.
