Welcome to the Igloo

The Igloo has grown to become an iconic location of the Illinois Valley area since it first opened on July 4th, 1937. Founded during the Great Depression by the original owners Louis "Louie" and Stephanie "Pat" Mazzorana, the Igloo continued to be family owned and operated into December of 2010. Carrying on the traditions and continuing to build the business for the future was then passed on to Rich and Chris Decker on December 16th, 2010.

Had lunch here yesterday and 🍔🥤lunch was delicious, as always. I am so glad you have reopened for indoor dining.

Today, in Peoria, my daughter and I were out to eat, when we struck up a conversation with the manager. We mentioned how we used to live in Peru, and no joke, the guy says, “did you ever eat at the igloo?” 🤣🤣 I said, “All the time!” Keep up the good work Rich and Chris!
