Wilmington Dairy Queen

Dairy Queen's connection to Illinois and Route 66 starts with founders John Fremont McCullough and his son Bradley, who developed the soft-serve formula in the late 1930s and partnered with Sherb Noble to open the first DQ in Joliet in 1940. The Brazier menu, with its grilled hot dogs and burgers alongside ice cream, was added system-wide in 1957 and helped DQ become a full meal destination rather than just a dessert stop. The Wilmington location reflects this tradition, with a Brazier-style full menu in addition to the famous soft-serve.

The original Joliet store stayed open for fourteen years and is now being interpreted by the Joliet Area Historical Museum as part of broader Route 66 preservation work. JAHM acquired the original building in October 2023 with plans to develop it into a small museum and visitor stop during the 2026 centennial. The Wilmington DQ is therefore a natural pairing for travelers interested in DQ's origin story.

The Blizzard, introduced in 1985, has become the chain's most recognizable product worldwide. The Wilmington location rotates flavors monthly and runs seasonal promotions including a summer S'mores Blizzard, an autumn Pumpkin Pie Blizzard, and a winter Peppermint Hot Cocoa version. Soft-serve cones and dipped cones remain the most ordered item by Route 66 travelers, and the dipped cone in cherry or chocolate is a particular favorite for photographs.

Prices at the Wilmington DQ are standard for the chain, generally lower than urban locations elsewhere in the Chicago region. A small soft-serve cone runs around $3, a medium dipped cone $4, and a regular Blizzard between $5 and $7 depending on flavor. The Brazier side of the menu includes the Original Cheeseburger, the Bacon Cheese GrillBurger, hot dogs, chicken strip baskets, chili dogs and curly fries. Combo meals run $10 to $14 and include drink.

Seasonal specials and limited-time offers rotate regularly. Watch for the Summer Blizzard menu in June and July, the Pumpkin Pie Blizzard in September and October, and the holiday Mint Oreo Blizzard in December. The location accepts credit cards, mobile payment, and participates in the DQ loyalty app, which offers occasional discounts and a free Blizzard for sign-up.

For families with young children, the kids' menu includes a small soft-serve cone, hot dog or chicken strip basket combos with juice or milk. High chairs are available in the small indoor dining area, and the drive-thru can accommodate larger family vehicles. The location is well-suited for a quick stop during a longer Route 66 day; most orders are filled in five to seven minutes even during the dinner rush.

The Wilmington DQ sits along Water Street, very close to the original 1926 Route 66 alignment through town. It pairs naturally with a visit to the Gemini Giant at South Island Park, antique shopping in historic downtown, and a stop at the Mar Theatre. Most travelers stop here for an ice cream cone or quick lunch in between longer activities; few make it a destination meal, but the Brazier menu can handle a full dinner if needed.

Summer weekends are the busiest period, with the soft-serve window often producing lines of ten or more during evening rushes. For shorter waits, target weekday afternoons or after 7 p.m. when crowds thin. Winter hours can be slightly reduced, with closing time shifting to 8 p.m. instead of 9. The location maintains its full menu year-round, however, including soft-serve.

For Route 66 travelers continuing south, the next DQ stop is in Pontiac, about thirty miles down the road. The next one north is in Joliet near the original site that JAHM is preserving. Visiting both bookends an Illinois Route 66 day with a soft-serve theme that ties together one of the Mother Road's most enduring food legacies.
