AI Now Takes Your Drive-Thru Order at Taco Bell, Dairy Queen and White Castle

Kristen Charpentier figured something was off the moment she pulled up to a Dairy Queen drive-thru speaker in Cary, North Carolina. The voice taking her order was too polite, too smooth, no dead air, no fumbled words. She asked the worker at the window. AI had taken her order, according to Wired, which first reported her experience.

Taco Bell announced in July that it has deployed AI ordering at 890 drive-thru lanes, more than 10% of its US locations, according to Wired. Dairy Queen is rolling the technology out across 25 states with plans to eventually put it in every restaurant. White Castle already runs an AI system named Julia in 12% of its locations, and every new White Castle store now opens with Julia taking orders from day one.

The numbers on adoption are still small in absolute terms but rising fast. Intouch Insight's annual Drive Thru Survey found roughly 4% of US fast-food locations used voice AI in 2024. That climbed to 5% last year, and early research now puts it around 6%, according to Wired. Sarah Beckett, vice president of sales and marketing at Intouch Insight, told Wired the chains that spent three years testing this tech are done testing. "They're going to start scaling this massively," she said.

This isn't new corporate enthusiasm. McDonald's started the chase back in 2019 when it bought AI startup Apprente and built McD Tech Labs around it, according to Wired. Del Taco and Dairy Queen partnered with Presto. Panda Express and White Castle went with SoundHound. Taco Bell teamed up with Nvidia and Omilia. Every chain promised the same thing in press releases: faster orders, fewer mistakes, better upselling than a human could manage. Wired notes the industry hit "a reality check" after those early rollouts, though the technology has since matured enough that chains are committing to it at scale rather than pulling back.

The Profitability Split

While voice AI grabs the headlines at the drive-thru window, a bigger shift is happening in the back office. Restaurant365, a restaurant management software platform, surveyed more than 420 restaurant operators for its 2026 State of the Restaurant Industry Mid-Year Report and found a widening gap between operators using AI and those who aren't, according to the Food Institute.

Sixty-two percent of operators using AI for back-office functions reported reduced labor costs. Steve Demchuk, Restaurant365's chief product officer, called it the "restaurant profitability gap" in comments to the Food Institute. He said back-office AI adoption has more than doubled since January, with users reporting meaningfully better results on food costs and operational efficiency.

Fewer operators are leaning on menu price hikes to protect margins during ongoing inflation. Just 52% raised prices in response to food-cost pressure, the survey found, with more operators instead turning to inventory management, waste reduction, and supplier optimization.

Traffic is also coming back faster than expected. Only 28% of operators reported traffic gains at the start of the year; by mid-year that number hit 46%, and 62% expect growth in the second half of 2026, according to Demchuk.

But he warned that rising traffic won't lift every operator equally. "The operators who turn their data into faster, smarter decisions will convert that traffic into margin, and the distance between them and everyone else is widening in real time," Demchuk told the Food Institute.

For operators who haven't adopted AI, the holdouts aren't stubborn for no reason. Data privacy is the top barrier, cited by 37%, followed by confidence in output accuracy at 34%, implementation cost at 29%, and just not knowing where to start at 18%, according to the survey. Those are legitimate operational concerns for small franchisees running on thin margins, not Luddite resistance.

Hospitality as the Counter-Bet

Not every chain is betting the model on automation alone. Restaurant Business reported that McDonald's, Starbucks, and Burger King are simultaneously investing in more human hospitality even as they digitize ordering. A remodeled McDonald's in Chicago runs mostly on kiosks, but the dining room was staffed with employees checking on customers repeatedly during a lunch rush, according to Restaurant Business.

Starbucks is adding "coffeehouse coach" roles. Burger King is renaming its managers "Your Way Champions" as part of a hospitality push. Burger King President Tom Curtis told Restaurant Business, "Ultimately, it's the restaurant experience that matters."

Technomic, Restaurant Business's sibling research firm, tracks customer service scores across 160 major chains. Robert Byrne, Technomic's senior director of consumer research, told Restaurant Business that chains in the top fifth for customer service scores averaged 11% sales growth last year. Drive-thru coffee chains like Dutch Bros and 7 Brew have built entire business models around in-line human greeters, with Byrne noting their service scores "outpace those of your Ruth's Chris, your Fleming's and whatnot."

So the industry is placing two bets at once: automate the transaction, but staff up the humanity around it. Whether AI voice systems and human hospitality can coexist at the same drive-thru window, or whether one eventually crowds out the other as chains chase Taco Bell's and White Castle's per-location savings, is an open question heading into the back half of 2026.
