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.

Diner in Illinois!

The Food Network website selected The Igloo as the best diner in the state of Illinois!

Thanks Joe for telling me how to make em. Southerners just don't understand why we love our pork tenderloins.

Congrats again! Will have to check out the plaque next time I come in!! Well deserved!!!

Congratulations and will stop by when I come back to visit this year sometime. I miss the Igloo very much and their food, I live in NC and no one serves Pork Tenderloins but Culver’s and they just aren’t like the Igloos !

Congratulations I come here every time I am in Illinois. ( I live in iowa now) I Love it. My sister worked here about 40 years ago. We still love it. Always the best

Congratulations!!! I wish you could ship one of those sandwiches to Florida I've been missing them since I moved. Well deserved!!

WOW! When I lived in Peru we went there all the time.My husband loved their pork sandwiches

Pete & Shorty's in Clearwater, Fl is an Iowa bistro and serves these sandwiches. People love them.

I grew up in Peru going there, now live in Streator and love going back

One of my all time favorite places!!! Congrats!

Congratulations!! Was in last week and they're still fantastic!! And you can't find these in Texas!!

That's awesome! Congratulations!

Congratulations (again!)!!! It’s truly a staple of Peru!!!

The Illinois Valley knew that a long time ago! Congratulations!

Congratulations from Texas from a guy who spent a bunch of his money there in my formative youth.

Congratulations on this prestigious award!! A definite stop when I am back home.

Fabulous!!! Awesome honor!!!🎉

Congratulations, and well deserved.
