Bring in the flyer below or show it on your smartphone and 20% of the proceeds will benefit Chicagoland Dog Rescue! If you are going through the drive-thru, you must inform the first order taker for it to count. We also recommend checking that FUNDRAISER is printed on your receipt, as sometimes orders get missed at checkout. A manager can adjust the order before you leave the restaurant. Please note: online, delivery and catering orders as well as the purchase of gift cards are NOT counted towards fundraiser sales. Flyer is valid only at participating Portillo’s and at specific date and time listed.
