Walking into Au Cheval feels like stepping into burger paradise, where the aroma of sizzling patties and toasted buns fills the air with pure temptation. This West Loop gem has achieved legendary status thanks to its double cheeseburger, a towering masterpiece that food critics and hungry diners alike consider one of the best burgers in America.
Two thin beef patties are stacked with gooey American cheese, with optional add-ons like crispy bacon or a perfectly runny fried egg that turn the burger into a glorious mess with every bite.
The secret lies in the quality of ingredients and the meticulous attention to detail that goes into every single burger. Each patty is cooked to juicy perfection, creating a crispy exterior while maintaining a tender, flavorful center.

Lines often stretch out the door, with wait times reaching several hours during peak dining periods. But ask anyone who’s experienced this burger, and they’ll tell you the wait is absolutely worth it for a taste of this unforgettable creation.
2. Cozy Dog Drive In – Springfield (2935 S 6th St, Springfield, IL 62703)
Route 66 travelers have been making pilgrimages to this roadside treasure since 1949, when the Waldmire family invented the corn dog on a stick and changed American fair food forever. The Cozy Dog isn’t just any corn dog—it’s the original, hand-dipped in a secret batter recipe that creates a perfectly golden, slightly sweet coating around a juicy hot dog.
Every bite delivers that satisfying crunch followed by tender, flavorful meat that makes you understand why this simple creation became an American classic.
The restaurant itself is a nostalgic time capsule, decorated with vintage Route 66 memorabilia and photographs that tell the story of America’s Mother Road. Families stop here to grab a taste of history, often leaving with full bellies and bags of frozen Cozy Dogs to take home.
The friendly staff treats every customer like an old friend, sharing stories about the restaurant’s fascinating past.
Beyond the famous corn dogs, the homemade root beer and hand-cut fries make the perfect companions to this iconic meal.
3. 17th Street Barbecue – Murphysboro (32 N 17th St, Murphysboro, IL 62966)
Smoke billows from the pits at this barbecue mecca, where championship-winning ribs have put tiny Murphysboro on the culinary map for serious meat lovers everywhere. Mike Mills, the pitmaster extraordinaire, has earned countless awards and accolades for his baby back ribs, which are seasoned with his signature Magic Dust rub and slow-smoked to tender perfection.
The meat literally falls off the bone with the gentlest pull, revealing layers of smoky, savory flavor that need no sauce to shine.
What sets these ribs apart is the perfect balance of smoke, spice, and tenderness achieved through hours of careful cooking. The outside develops a beautiful bark that provides textural contrast to the succulent meat beneath.
Apple City barbecue sauce is available on the side for those who want an extra tangy-sweet kick, but purists often enjoy these ribs naked to fully appreciate the smoking technique.
The restaurant’s walls are covered with trophies and ribbons from barbecue competitions across the nation, testament to the serious craft happening in the kitchen.
4. Avanti’s Ristorante – Peoria (4711 N Rockwood Rd, Peoria, IL 61615)
Central Illinois residents have been obsessing over Avanti’s Gondola sandwich for decades, a creation so beloved it’s become part of the region’s cultural identity. This isn’t your typical Italian sub—it’s a warm, toasted masterpiece piled high with four different Italian meats, melted cheese, and a secret garlic spread that transforms every ingredient into something extraordinary.
The combination of salami, ham, pepperoni, and beef creates a flavor symphony that hits all the right notes.
Fresh lettuce and tomatoes add a cool, crisp contrast to the warm, melty center, while the house-made garlic spread provides an addictive punch that keeps people dreaming about their next visit. The bread is toasted to perfection, crispy on the outside yet soft enough to hold all the generous fillings without falling apart.
Each bite delivers multiple textures and flavors that work together in perfect harmony.
Locals often order multiple Gondolas to take home, knowing they’ll want another one as soon as the first disappears. The sandwich has inspired fierce loyalty among Peoria residents, many of whom consider it comfort food.
5. Pequod’s Pizza – Chicago (2207 N Clybourn Ave, Chicago, IL 60614)
Forget everything you think you know about deep dish pizza, because Pequod’s has created something entirely different with its legendary caramelized crust that borders on magical. The cheese is spread all the way to the edges of the pan, where it meets the scorching hot cast iron and transforms into a crispy, caramelized ring of pure deliciousness.
This technique creates a crunchy, almost lacy edge that provides the perfect contrast to the thick, gooey center loaded with toppings.
The sauce is tangy and bright, cutting through the richness of the cheese and adding a fresh tomato flavor that keeps each slice interesting. Toppings are piled generously, and the crust itself has a wonderful yeasty flavor that makes even the bones worth nibbling.
The whole pizza is baked until the cheese bubbles and browns in spots, creating pockets of intensified flavor throughout.
The cozy, dimly lit atmosphere adds to the experience, making you feel like you’ve discovered a hidden treasure. First-timers are often shocked by how different this style is from traditional deep dish.
6. Lou Malnati’s Pizzeria – Chicago (958 W Wrightwood Ave, Chicago, IL 60614)
When Chicagoans debate the best deep dish pizza in the city, Lou Malnati’s inevitably enters the conversation with its buttery crust that sets it apart from all competitors. The secret weapon is the crust itself—a rich, flaky base made with butter that tastes almost like a savory pastry and provides the perfect foundation for the towering layers above.
Fresh mozzarella cheese goes directly on the crust, followed by your choice of toppings, and then the whole creation is blanketed with chunky vine-ripened tomato sauce.
This reverse layering technique keeps the crust from getting soggy while allowing the flavors to meld together during the long baking process. The result is a pizza where every element maintains its distinct character while contributing to the harmonious whole.
The cheese stays creamy and stringy, the toppings remain flavorful, and that buttery crust stays remarkably crisp despite supporting all those delicious layers.
Lou Malnati’s has expanded throughout Chicagoland, but each location maintains the same commitment to quality that made the original famous. They even ship their pizzas nationwide for homesick Chicagoans.
7. Johnnie’s Beef – Elmwood Park (7500 W North Ave, Elmwood Park, IL 60707)
Since 1961, this no-frills stand has been serving what many consider the gold standard of Italian beef sandwiches, a Chicago specialty that inspires passionate devotion. Paper-thin slices of seasoned beef are piled impossibly high on fresh Italian bread, then dipped in flavorful au jus that soaks into every crevice of the roll.
The meat is tender and savory, seasoned with just the right blend of spices that enhance rather than overpower the natural beef flavor.
Ordering here requires learning the local lingo: you can get your sandwich dry, wet, or dipped, depending on how much au jus you want soaking into that bread. Most regulars go for dipped, accepting that they’ll need a stack of napkins to handle the gloriously messy result.
Sweet or hot peppers add a pop of flavor and texture, while giardiniera provides a spicy, vinegary kick for those who like heat.
The outdoor picnic tables are always packed with locals who’ve been coming here for generations. There’s something wonderfully democratic about eating at Johnnie’s, where everyone stands in line together.
8. Fried Green Tomatoes – Galena (213 N Main St, Galena, IL 61036)
Nestled in the heart of historic Galena, this charming restaurant has earned its reputation on the strength of its namesake dish that perfectly captures Southern hospitality with Midwestern charm. Thick slices of firm green tomatoes are coated in a seasoned cornmeal crust and fried until golden and crispy on the outside while maintaining a slight tang and firmness inside.
The contrast between the crunchy exterior and the tart, juicy tomato creates a flavor explosion that surprises first-timers and keeps regulars coming back constantly.
Served with a creamy remoulade sauce that adds richness and a subtle kick, these fried green tomatoes elevate a simple vegetable into something truly special. The restaurant sources local tomatoes when possible, ensuring peak freshness and supporting area farmers.
Each order arrives piping hot, with the coating staying remarkably crisp even as you savor each piece.
The cozy atmosphere and friendly service make dining here feel like visiting a friend’s home. The historic building adds character, and the location on Main Street makes it perfect for exploring Galena’s antique shops and galleries afterward.
9. Superdawg Drive-In – Chicago (6363 N Milwaukee Ave, Chicago, IL 60646)
Two giant hot dog statues named Maurie and Flaurie have been watching over this retro drive-in since 1948, beckoning hungry customers to experience a Chicago-style hot dog done absolutely right. The Superdawg itself is a pure beef hot dog with a natural casing that provides a satisfying snap with every bite, nestled in a poppy seed bun and topped with mustard, relish, onion, sport peppers, pickles, and tomatoes.
What makes it special is the perfect proportion of toppings to hot dog and the quality of each individual ingredient.
The whole creation arrives in a distinctive box alongside crispy crinkle-cut fries and a pickle spear, making the presentation as memorable as the taste. Eating in your car under the twinkling lights while vintage music plays through the speakers creates a nostalgic experience that transports you back to simpler times.
The carhops are friendly and efficient, delivering your order with a smile that feels genuinely warm.
This family-owned gem has resisted modernization, maintaining the same recipes and service style that made it famous decades ago. It’s a living piece of Chicago history.
10. Gene & Jude’s – River Grove (2720 N River Rd, River Grove, IL 60171)
Prepare for something completely different at this legendary hot dog stand where ketchup is forbidden and the unique preparation method has created a cult following. The hot dog comes buried under a mountain of fresh-cut french fries that are placed directly on top of the dog itself, creating a carb-on-carb masterpiece that shouldn’t work but absolutely does.
Mustard, onions, sport peppers, and relish complete the ensemble, with all the toppings mixing together in a gloriously messy combination.
The genius lies in how the hot fries slightly steam the bun while absorbing the flavors of the toppings and the juices from the hot dog. Every bite delivers multiple textures and tastes, from the crispy fries to the snappy hot dog to the soft, slightly soggy bun.
It’s comfort food elevated to an art form, unpretentious and utterly satisfying.
The tiny stand has barely changed since opening in 1946, with worn counters and a no-nonsense approach to service. You order at the window, grab your food, and eat standing up or in your car—no frills, just fantastic hot dogs that have earned their legendary status.
11. Manny’s Cafeteria & Delicatessen – Chicago (1141 S Jefferson St, Chicago, IL 60607)
Politicians, construction workers, and food lovers from all walks of life line up at this Chicago institution to experience corned beef sandwiches that define what deli meat should taste like. The corned beef is brined and slow-cooked in-house until it achieves that perfect tender texture that pulls apart with the slightest pressure, then it’s hand-sliced thick and piled ridiculously high between slices of fresh rye bread.
The meat is peppery, salty, and incredibly flavorful, with just the right amount of fat marbled throughout to keep it juicy.
Cafeteria-style service means you can watch the countermen build your sandwich right before your eyes, slicing the meat fresh for each order. The portions are enormous, often requiring two hands to hold the sandwich together, and even the biggest appetites struggle to finish everything on the plate.
Traditional sides like potato pancakes and matzo ball soup round out the menu perfectly.
The bustling atmosphere and diverse crowd create an energy that makes every visit feel special. Manny’s has been feeding Chicago since 1942, maintaining the same commitment to quality and generous portions.
12. The Original Rainbow Cone – Chicago (9233 S Western Ave, Chicago, IL 60643)
Five distinct flavors swirled together in perfect harmony have made this frozen treat a Chicago summer tradition since 1926, representing generations of sweet memories. The Rainbow Cone isn’t just ice cream—it’s an architectural marvel that stacks chocolate, strawberry, Palmer House vanilla, pistachio, and orange sherbet into one glorious cone that somehow tastes even better than the sum of its parts.
Each flavor remains distinct yet complements the others, creating new taste combinations with every lick as the flavors mingle on your tongue.
The Palmer House vanilla, studded with cherries and walnuts, adds a luxurious middle layer that ties the fruitier top to the chocolate base. The pistachio provides a nutty richness, while the orange sherbet offers a refreshing citrus note that cleanses the palate.
It’s a carefully engineered flavor journey that takes you from bright and fruity to rich and chocolatey.
Families have been making pilgrimages here for nearly a century, with grandparents introducing grandchildren to this iconic treat. The simple walk-up window and picnic tables keep the focus on the ice cream, which truly needs no distraction.
