Here is what IHOP says about today on their website:
Flip for Free Pancakes! February 28, 2012
Since beginning its National Pancake Day celebration in 2006, IHOP has raised nearly $8 million to support charities in the communities in which it operates. On February 28, 2012, guests from around the country are invited to celebrate National Pancake Day at IHOP and enjoy a free short stack of Buttermilk pancakes.* In return for the free pancakes, guests are asked to consider leaving a donation for Children's Miracle Network Hospitals© and other designated local charities.
Make sure to call your local IHOP to make sure they are participating then go enjoy some free pancakes! I know my family and I will be!
