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!

GREAT NEWS! We found out yesterday that ALL our employees have tested negative and have no symptoms for Covid!!! This includes Chris and I.
At the end of this week we will have been quarantined for 14 days and then start getting The Igloo ready to open again. Yea!
We plan on opening Wednesday 7/29 at 11 am.
Due to the continuous rise locally in Covid cases we are going to make some changes at this time.
First, we are going back to carry out orders only. No inside dining at this time. We still have table outside for exterior dining.
Secondly, anyone entering The Igloo will be required to wear a mask. We understand how some of you feel about this, but we feel the need to go with the recommendations to help eliminate the possibility of going through this again.
Thirdly, we decided to close Mondays as well as Tuesdays at this time. We feel the need to do this to contribute to Chris’s and I health and well-being during this stressful time due to the amount of hours we put in. Chris and I aren’t spring chickens anymore 😦. This will be temporary and reopen Mondays when the time is right.
Our hours will now be Wednesday through Sunday 11-8.
We thank you, as always, for your understanding and continued support!!!

Just talked with Lasalle County Health Department. They said that covid is not foodbourn and that since customers have not spent a straight 15 minutes within 6 feet of any employees, affected or not, that the risk is very very very low. Any questions they recommend calling your local health department. ... See MoreSee Less

I commend you for doing everything you are supposed to do and telling the public. This is the type of business that should be trusted as they are being honest and taking all precautions! Best of Luck!!! 👏🏽

This is so responsible of you! The Igloo deserves all the support the community can muster. Bless you all!

I too applaud you for your transparency! We know you have followed all protocol in an effort to keep your customers and self healthy. Unfortunately no one who works in the public can guarantee immunity. He/she won’t know if there was exposure by a customer who isn’t showing symptoms, someone else at work, or in your family circle. I just pray your employee is recovering and the symptoms are mild. I also hope your other employees will test negative.

Our family commends you for how you are making this public and keeping everyone updated. I hope others can learn from your responsible actions. I know we will choose the igloo more from now on and I think others will too. I mean this just adds to the fact that you have the best porks ever!

Great job keeping the public informed and protected!

We are behind you 100%!

Are you going to reopen? At least for curbside service?

How long will you be closed?

Such a trying time for all Americans. God bless you for posts & keeping us informed. Stay well & I hope your employee is going to be okay, You are all in my prayers!

That’s good news! Thank you for keeping us informed! (Prayers that your employee is ok). Hope you are all healthy & able to open soon!

Thanks for keeping us all posted. Hope you all stay safe.

You're doing everything right. Can't wait till you open again

Hope you’re back up and running very soon.

Hope to see you open when I get there!!!! ❤️🙏🏼🤞🏼

We have talked to the LaSalle County Health Department. Their major concern is anyone being in Close contact with this person for 15 minutes or more. But to be extremely cautious we have chosen to remain closed for a bit to give ourselves and our employees time to be tested. Will update when needed ... See MoreSee Less

Are there concerns for anyone who ate at the diner during this employees recent shifts per the Health Department? Thank you for your transparency- it’s such a responsible thing to do and not the easiest path to take!

Thank you for being responsible business owners. Take care of yourselves and be safe.

I applaud you for taking precautions and being a safe local business! When you reopen I will be ordering more! Thank you for caring for your employees and family ❤️❤️

So sorry about this happening!I know you have done everything in your power to keep everyone safe!!

SO here in the East Coast, we are asking for customers name & phone number & along with their servers name & table number for reasons exactly like this...might want to think about it as well as other area restaurants there👍🏼😷😎

Thank you for trying to keep our community safe. Prayers it is isolated to one employee and the rest of you are safe.

We stopped in last week for lunch and we were very impressed on how you are making distancing available for your patrons. Everyone were wearing masks and seating was very safe. Thank you! So sorry about your troubles praying for all to be safe.

My husband ate there Thursday- was that person working then? If so I’d like to know so he can get tested- we have someone in our family who is vulnerable

I enjoy the food there , ive seen how cautious you are with all of this , been in there multiple times throughout covid . I pray noone else gets it or has it . Thank you for keeping us posted .

You are a class act my dear friends. Julie and I have you in our thoughts and prayers.

We know and share your concerns. We are concerned for ourselves as well. We are working with a minimum staff and we all have contact with food one way or another. We took it upon ourselves to close the restaurant until we know where we go from here. We have contacted the LaSalle country health department for further guidance. We thank you so very much and will keep you updated ... See MoreSee Less

We just found out an employee of ours tested positive for covid this morning. We are not 100% sure of correct protocols at this time so we will not be open today. Will keep you all posted. Thanks ... See MoreSee Less

I'm very proud to support a business that cares about the public safety and is brave enough to post. We will be sending good vibes for a fast and healthy recovery.

Hope this is helpful: -Contact the local health department to make them aware. -Contact every single individual (employees and diners) who came into contact with this individual (as best as possible). That is critical to minimize any potential spread. Those individuals all need to quarantine for 14 days and likely be tested. -Have a professional company deep clean the restaurant with products known and approved to kill the virus. Consider a HEPA filter to temporarily purify the air. Stay safe 💛

Thank you for your honesty! Speedy recovery to your employee and hoping no one else gets sick. We will be back!

Thank you for your honesty. You’ll be back better than ever once this done.

Thoughts and prayers going out . We will always support the Igloo ! Great food and friendly people !

goes to show the importance of that person wearing a mask like the igloo owners make them wear

Thank you for being honest about this. Prayers for the employee for a quick recovery and for everyone else that they don't have it. Can't wait until you are back open.

Thank you for being candid. It’s businesses like yours that I will continue to patronize because you care.

I have not been to your place of business as of yet but I will when you reopen! Kudos to you on being honest and open and obviously caring about your customers and employees!

Wishing them to not have a severe case, and it doesn’t get too spread. Stay safe and let’s not all be negative.

Now I know why your not answering your phone . Thanks for being so cautious ! Hope everyone is ok!

I am so sorry you all are going through this. It is so nerve wracking when it hits home. Be safe.

14 days minimum closure and u best get folks in hazmat suits to clean your place.

Have other employees who were in contact with that person get tested as well. Be safe ❤️

Any company certified in healthcare cleaning can do the cleanup. Mine had it , but I am not taking new customers. Just letting you know what to ask for when searching for cleaning companies.

My prayers for the full recovery of your employee. Thank you for being honest and letting the public know.

Thank you for your honesty & concern for patrons. Wishing your employer a quick recovery.

With symptoms or asymptomatic? Has a second test been done to reduce chances of a false positive?

Thank you for keeping the public informed. #lovetheigloo

Thank you for sharing. I appreciate it.

Thank you for sharing ❤ we will continue to support you guys always!

Thanks for caring. Hoping your employee has a complete recovery.

Thanks for sharing and being cautious.

Thank You for doing what needs to be done to be safe for all!!

I was in there this past Thursday . Do I need to do anything. I am really hoping you are all ok but now we can be infected
