IHOP will offer patrons the chance to indulge in a free stack of its traditional buttermilk pancakes tomorrow, Feb. 28, from 7 a.m. to 10 p.m. The event marks the 7th annual IHOP National Pancake Day.

With each stack, IHOP encourages guests to donate to the Children’s Miracle Network Hospitals, a charity devoted to raising money for local pediatric hospitals across the United States. IHOP hopes to raise $2.7 million for the charity this year, bringing their total contributions to $10 million.

Take advantage but take care—lines can become hectic as hungry patrons swarm pancake stores nationwide.
