To celebrate the St. Patrick's Day holiday, all Eat'n Park restaurants are offering their famous smiley cookies in the shape of a shamrock.

The family-friendly chain of restaurants known for giving away free smiley cookies to their youngest customers, expect to sell out these green varieties really fast. Their black & gold Pittsburgh Steeler cookies and their Valentine's Day cookies were strong sellers.

If there isn't a Eat'n Park restaurant near you, they sell their cookies online to all 50 states.
