When most people think of Illinois food, Chicago-style deep dish pizza and Chicago hot dogs are the first to come to mind. And while those are absolutely worth a bite (or two), the state’s culinary story goes far deeper than city staples. From quirky small-town diners to legendary sandwiches, Illinois is full of flavors that are every bit as authentic—and worth the trip.

The Horseshoe Sandwich – Springfield’s Legendary Indulgence

🍞🍟🍳 Born in the state capital, the horseshoe sandwich is a Midwestern masterpiece of comfort food. Here’s how it stacks up: two slices of thick toast, your choice of meat (hamburger, ham, turkey, or even fried chicken), a generous pile of crispy fries, and a smothering of rich cheese sauce.

Invented in Springfield in the late 1920s, the horseshoe has since become a must-try for anyone road-tripping through central Illinois. Many restaurants in town claim their version is “the best,” so the only way to decide is to try more than one.

Italian Beef – A Chicago Classic with a Juicy Twist

🥖 Chicago’s Italian beef sandwich is simple in theory but perfect in execution. Thinly sliced roast beef is slow-cooked with Italian herbs, piled into a crusty roll, and topped with sweet peppers or spicy giardiniera. The finishing touch? The “dip”—dunking the whole sandwich into savory au jus for a messy, delicious bite.

This Chicago staple has inspired endless debates on who makes it best (Al’s, Portillo’s, and Mr. Beef all make strong cases). Wherever you try it, make sure plenty of napkins are on hand.

Rainbow Cone – A Tower of Happiness

🍦 Summer in Illinois wouldn’t be complete without a stop at Original Rainbow Cone in Chicago. Since 1926, this cheerful ice cream tower has stacked five flavors—orange sherbet, pistachio, Palmer House (New York vanilla with cherries and walnuts), strawberry, and chocolate—into one unforgettable cone.

It’s whimsical, nostalgic, and a little bit messy, which is exactly what makes it such a beloved Illinois tradition.

Small-Town Diners Worth the Drive

🚗 Sometimes the best Illinois meals are found off the beaten path. Across the state, small-town diners serve up hearty breakfasts, homemade pies, and dishes that tell the story of the communities they’ve been a part of for generations.

• Dell Rhea’s Chicken Basket (Willowbrook): Fried chicken that’s been legendary since the 1940s, right along historic Route 66.
• Charlie Parker’s Diner (Springfield): A Quonset hut diner famous for oversized pancakes and featured on Diners, Drive-Ins and Dives.
• Palace Diner (Mattoon): A no-frills local favorite with down-home classics.

These roadside gems are more than just places to eat—they’re places to connect with Illinois hospitality.
