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.

RICH'S FAVORITE BURGER

When I want a Burger for myself, this is how I roll... I start with 2 patties of Fresh Ground Angus Chuck. Then take a Pretzel Roll, butter it, and grill it to bring out a nice warm full Pretzel taste. Next, I sauté' Diced Bacon & Onions. I put it all together and top it off with an awesome Cheddar Cheese Sauce. It's my favorite way to have a Burger! I think you'll enjoy it too!

It's a toss up which I like best - The Igloo or Verrucchi:s! Don't get to either often enough!
