IHOP is having a National Pancake Day Celebration tomorrow- Feb. 24th. You can receive one short stack (3 pancakes) for free with no purchase. They are asking for a donation to go to local children's hospitals. http://www.ihoppancakeday.com/
I know Denny's had a free GrandSlam a few weeks back. The news reported the lines were long. Recently McDonalds has been having the free small fries on Tuesday too. I guess a lot of business are trying to create hype with the economy being so bad.
