Sure, it's hump day. But did you know it's also National Waffle Day?

Celebrated every year on the date the patent was issued for the waffle iron, this food holiday isn't as made-up as some of its counterparts. However, it's still a great opportunity for you to snag free food from restaurants running waffle promotions.
