The Robot at the Drive-Thru Window Is Back, and This Time It Might Stick
After a rocky first attempt, fast-food chains are quietly rolling AI voice ordering back out to millions of customers. A few are winning. A few are still figuring it out.
Key points
- Roughly 6 percent of US fast-food drive-thrus now use AI voice ordering in 2025, up from 4 percent in 2024.
- Taco Bell has deployed AI at 890 drive-thru lanes, more than 10 percent of its US locations.
- White Castle's AI system, named "Julia", cuts an average of 21 seconds off service time compared to the industry standard.
- McDonald's pulled its first AI drive-thru programme in 2024 but is now testing a new system with Google at five US locations.
- Chick-fil-A, Dutch Bros and 7Brew have chosen not to use AI ordering, citing the value of human interaction.
Kristen Charpentier knew something was off the moment she pulled into a Dairy Queen drive-thru in Cary, North Carolina. The voice was too polite. Too smooth. Every sentence ended with a please or a thank you.
She'd worked that exact job as a teenager. So when she reached the pickup window, she asked the employee directly. A robot had taken her order.
Charpentier wasn't alone. As Wired reported, thousands of US drive-thru customers have placed orders with AI voice systems, often without realising it until the food arrived. An AI voice agent, software that listens to your order and responds in real time with no human on the other end, now greets customers at roughly 6 percent of fast-food drive-thrus, up from 4 percent in 2024.
How did we get here?
McDonald's set this in motion in 2019 when it bought a drive-thru AI startup and built an in-house tech division around it. Other chains rushed to follow. Faster service, lower costs, fewer errors: that was the pitch.
The reality was far messier.
Social media filled with clips of AI systems misfiring. One viral video showed a McDonald's AI piling 260 Chicken McNuggets onto a single order. Another caught the same chain's AI adding bacon to an ice cream. At Taco Bell, a customer reportedly ordered 18,000 cups of water without the system blinking. Research firm Intouch Insight found that early AI drive-thrus scored lower than humans on both friendliness and order accuracy. Accents and dialects tripped up the software constantly. McDonald's eventually sold its AI division to IBM and shut the whole programme down. Del Taco rolled back its test.
So why is it growing again?
Because a few chains never stopped, and the technology improved while they kept at it.
White Castle has run its AI system, a voice agent called Julia, for four years through a partnership with SoundHound AI, a voice recognition company. The chain says Julia has made employee shifts run more smoothly and, on average, cuts 21 seconds from service time. White Castle also cracked Fortune's top 20 best workplaces in retail last year. We first covered White Castle's AI rollout on 3 August 2026, when voice AI was already drawing attention well beyond the restaurant industry.
Taco Bell now runs AI across 890 lanes. Dairy Queen is expanding across 25 states, with plans to eventually cover every location. McDonald's is trying again, this time partnering with Google at five US test sites, using a system that handles orders in both English and Spanish.
| Chain | AI scope | Partner |
|---|---|---|
| Taco Bell | 890 lanes (10%+ of US locations) | Nvidia, Omilia |
| Dairy Queen | 25 states, national rollout planned | Presto |
| White Castle | 12% of locations, all new sites | SoundHound |
| McDonald's | 5 US test locations (2025) |
What does this mean for customers?
For most people the immediate change is modest: a synthetic voice takes your order instead of a person. At White Castle you can ask for a human at any point.
The bigger question is what happens to jobs. Fast-food executives say AI isn't replacing workers; the people previously on headsets are being moved to other tasks in the kitchen or at the window. Employment numbers at White Castle have held steady. Replacing human cooks and cashiers with machines is a far harder problem that no chain has solved.
Not every chain thinks the trade-off is worth it. Chick-fil-A consistently tops customer satisfaction surveys for drive-thru friendliness and has never moved toward AI ordering. Dutch Bros and 7Brew have made the same call. "Every brand has to make choices that fit its," 7Brew's chief marketing officer told Wired, citing genuine human connection as the starting point for hospitality.
Some customers share that instinct. "I want to be able to say hi to a human being," one Virginia Wendy's customer told the outlet, after an AI voice left him waiting for a person who never arrived.
With only one in seventeen drive-thrus currently using the technology, there are a lot of first encounters still ahead. The chains scaling up are betting familiarity breeds acceptance. What's worth watching is whether order accuracy data, not just speed figures, improves enough to quiet the sceptics before the next wave of viral mishaps gives them fresh ammunition.
Common questions
How can you tell if an AI is taking your order?
The voice will sound consistently smooth and pleasant, with little background noise or hesitation. If you're unsure, ask the speaker directly whether you're talking to a person or an automated system.
Will this cost people their jobs?
So far the evidence says no, at least not directly. Chains report that workers previously on headsets are moved to other roles. Replacing the broader workforce with machines is a much harder problem the industry hasn't solved.
