IHOP, and its charitable partners Children’s Miracle Network Hospitals, Shriners Hospitals for Children and the Leukemia & Lymphoma Society teamed up to celebrate National Pancake Day. On March 7, participating locations invited customers to enjoy a complimentary short stack of pancakes to commemorate the day, and encouraged diners to donate to one of IHOP’s charitable partners with the goal of raising $3.5 million for children battling critical illnesses.
