Come celebrate the “flounder” of Ivar’s restaurants’ 107th birthday on Tuesday, March 20! Enjoy a $1.07 entrée, when you purchase another. The deal happens when you say “Happy Birthday Ivar!”. The birthday bargain will be available at all 23 Ivar’s quick-serve Seafood Bars (except stadium locations), Ivar’s Acres of Clams, Ivar’s Salmon House and Ivar’s Mukilteo Landing. The first 107 visitors at Ivar’s locations will receive a complimentary cupcake with their meal.

Ivar’s Seafood Restaurants began on Seattle’s waterfront in 1938 by Ivar Haglund. Today, there are Ivar’s fast casual Seafood Bars, three Fish Bars, and three full service restaurants. Ivar’s also operates concessions throughout the Puget Sound.

Plus, you’re invited to use your smartphone, or any technology, to sing “Happy Birthday Ivar”, and win an Ivar’s gift card worth 107 clams ($107).

All you have to do is upload the video to O-Fish-All Ivar’s Club Facebook page. Ivar’s says have fun with it and sing it loud and proud. Bonus points will be given for actually being at one of Ivar’s locations. Contest ends Tuesday, March 20. The lucky winner will be announced later in the month.
