In the shadows of the Dan Ryan Expressway, Express Grill at 1260 S Union Ave is a legendary portal to "Old Chicago." This isn’t a trendy bistro or a polished diner; it is one of the last true keepers of the Maxwell Street Polish tradition, having stood side-by-side with its famous rival, Jim's Original, for decades.
When the historic Maxwell Street market was razed, Express Grill moved its walk-up window to Union Avenue, bringing with it a 24/7 grit that fuels everyone from night-shift workers to late-night clubgoers.
The Express Grill "Classic" Identity
The Sautéed Onion Perfume: You will smell Express Grill before you see it. The air for a block in every direction is thick with the scent of onions being caramelized on a massive flat-top grill. At Express Grill, "extra onions" isn't a request; it’s a lifestyle—piled high until the bun is nearly invisible.
The "Free Fries" Tradition: In a nod to the generosity of the old market days, every sandwich comes with a heap of crispy, golden fries tucked into the bag at no extra charge. It’s the ultimate Chicago value proposition.
The "Bone-In" Secret: While the Polish Sausage is the star, the real "insider" order is the Pork Chop Sandwich. It is served with the bone still in—a hallmark of authenticity that requires a bit of tactical eating but rewards you with flavor you can't get from a boneless patty.
24/7/365 Reliability: Like a lighthouse in the urban sea, Express Grill never closes. Whether it’s 4:00 AM on a Tuesday or mid-day on Christmas, the window is open and the grill is hot. It is the city’s most dependable "emergency" kitchen.
The Maxwell Street Ritual
There is a specific "flow" to eating here. You walk up to the stainless-steel window, place your order, and receive your food wrapped in wax paper and stuffed into a brown paper bag that quickly turns translucent from the delicious grease. There is no indoor seating—the "dining room" is the sidewalk or the hood of your car.
The Vibe: It is "Industrial Heritage." It’s fast, loud, and unapologetically salty. It represents the Chicago that works with its hands—a place where the only thing that matters is the snap of the sausage and the sweetness of the onions.
The "Big Three" Menu Pillars
Item The "Express" Way Maxwell St. Polish A seasoned beef and pork link, grilled until the casing snaps, loaded with mustard and hot sport peppers. Pork Chop Sandwich A thick, bone-in chop seared on the flat-top, served with those signature sweet onions. Double Cheeseburger For those not in a sausage mood, it’s a classic, griddled "smash" style burger that rivals the city's best. Fast Facts
Parking: There is a small, high-turnover pull-in area, but be prepared to play "musical chairs" with your car during peak hours.
Payment: Unlike the cash-only days of the past, they now accept debit and credit cards, making that 3:00 AM craving easier to satisfy.
Pro-Tip: Always ask for "hot peppers" (sport peppers) on the side if you aren't sure of your spice tolerance—they have a sneaky, vinegary kick.
The most interesting reviews
- The best street food hands down! Made right in front of you! && to make it even better the prices are sooo affordable! I fed me and my kids for literally less then $30. I’m not originally from Illinois and I recently moved but I will for ever miss this restaurant and go back for some every time I visit the Windy City! Ps, their open late so perfect greasy food after a good night out !
- I am happy to say that the place hasn't changed a bit in the 20+ years I have been going. Porkchop sandwich and polish sausage are still perfection.
- The food was quite enjoyable as I discovered this place while visiting from another state. Nice
