Some of the best meals in Illinois hide behind plain signs, worn booths, and a coffee pot that never seems to run dry. You walk in expecting a quick bite, then a plate of tender liver smothered in sweet, golden onions lands in front of you and suddenly you are a kid again at Grandma’s table.
This old-fashioned dish is getting harder to find, which makes every diner that still serves it feel like a small treasure. If you are hungry for comfort and curious about where it still lives, these spots are worth the drive.
1. Daley’s Restaurant, Chicago, IL

Liver and onions shows up right on the breakfast menu, which is a rare and happy surprise. Prefer it later in the day?
Pair it with rice and gravy, collard greens, macaroni and cheese, and a cornbread muffin for a plate that eats like a family Sunday dinner. Smothered pork chops, fried chicken, and French toast round out the lineup, and the homemade biscuits are a must.
