💜 Our hearts are with the family and friends of Daniel Joseph Charles Gravitt.

The I Don’t Know family extends our deepest condolences to Daniel’s loved ones. No family should have to face such a heartbreaking loss alone.
If you’re able, please consider stopping by on Sunday, July 12, making a donation, or supporting the official fundraiser.

Our thoughts and prayers are with everyone whose lives Dan touched. May his spirit and the lessons he taught remain with you always, and may his family find comfort in the love and support of this amazing community. 🙏🏻💜

Happy 618 Day, Southern Illinois! 💜

Today we're celebrating the community that has supported us from day one.

As a small, family-owned business, we're grateful to be part of the 618. From school events and fundraisers to family dinners and lunch breaks, you've made IDK more than a restaurant...you've made it a gathering place.

To say thank you, all sandwiches are just $6.18 today only! Valid on all call-in, dine-in & take out orders.

Local food. Local people. Local pride.
