Our Story

Humble Beginnings

Happy-Moose-Mentor.jpg

It’s a real-life American-dream-come-true story. Pat Tsilianidis, a Greek immigrant, was working as a janitor at Great Lakes Mall in Mentor before he started cooking at a local restaurant and eventually bought a diner on East 185th St in Cleveland. He owned and operated that diner for 36 years, but also grew his family.

Pat loves the restaurant business and his family. That’s why he’s so happy to be a co-owner of Happy Moose Bar & Grill along with his two sons. He got to combine his love for the restaurant business and for his family into one great business.

The Tsilliandis family wanted to provide a place for the Cleveland community to gather and enjoy America’s favorite past-times — great food and sports! The first Happy Moose Bar & Grill opened in Mentor and invited sports fans and food fans alike to come inside, eat tasty burgers, drink cold beer, and watch great games.

And the rest is a history as happy as the Moose himself.
