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.

PRETZEL PIZZA BURGER

Been a while since you had a pizza burger? This unique blend of flavors is the one to try! Two fresh ground beef patties, with a slice of mozzarella in between, slices of pepperoni, and top it off with a rich marinara sauce on a warm pretzel roll for a fantastic taste! "It's OMG good!"

Delicious, messy but delicious especially with my vanilla shake

This sandwich is AMAZING.....perfect blend of flavors. The only thing better is if you'd use the marinara sauce from this sandwich to permanently add either spaghetti and/or tortellini marinara to your menu!!!
