Restaurant AI voice ordering in 2026: lessons from the big chains

Two of the biggest names in fast food looked at the same technology this year and walked in opposite directions. One put AI order-taking in nearly 900 drive-thrus. The other scaled back after customers drove away rather than talk to a bot. If you run a restaurant and a vendor has pitched you an AI phone or ordering system, that split is the most useful thing you can study.

What happened

In July, Restaurant Dive reported that Taco Bell expanded its partnership with voice AI company Omilia, whose system now runs in more than 890 U.S. Taco Bell locations across 38 states. Omilia says locations using it have seen higher employee retention because staff can focus on hospitality instead of taking orders. The rollout followed a rough stretch in 2025, when parent company Yum slowed deployment after complaints and pranks, including an order for 18,000 cups of water.

In September, Nation's Restaurant News reported that Burger King is rethinking its approach. It is testing voice AI in roughly 50 to 70 locations and plans to make it easier to reach a human. A Burger King technology executive said pilot restaurants saw drive-offs "because guests don't want to talk to a bot." Technomic data presented at the same industry conference found only 23% of consumers find ordering from an AI drive-thru bot appealing, while 46% find it unappealing.

McDonald's, which ended an earlier voice AI test with IBM in 2024, is trying again. Restaurant Dive reported that the chain plans to use AI for drive-thru ordering, inventory management and order accuracy.

Why it matters for your business

Most independent restaurants do not have a drive-thru. But they do have a phone that rings during the dinner rush when nobody can answer it, and that is where most AI ordering pitches to small operators land.

The chain experience teaches three things. First, the technology can work at scale, as Taco Bell shows. Second, forcing customers to use it backfires, as Burger King found. Third, the customers who are not sure about it are not a small group. When nearly half of consumers in the Technomic data find AI ordering unappealing, you cannot treat their discomfort as a rounding error.

Independent restaurants also live on regulars and word of mouth. A chain can absorb some annoyed drive-thru customers. A neighborhood spot with a bot that mangles a regular's usual order, or cannot answer an allergy question, takes a real hit.

The case for trying it is still strong. A missed call during a rush is a lost order. Staff turnover in restaurants is high, and anything that frees a server or host from the phone gives that person back to the guests in front of them. Taco Bell's claim about retention, while it comes from its vendor, points the same way.

What we'd do

• Start with after-hours and overflow. Let AI answer when nobody else can: before open, after close, and when the line is already full. Do not put it in front of every call on day one.
• Make "talk to a person" instant. One word or one button, every time. Burger King's lesson is that a trapped customer is a lost customer.
• Never let a bot guess about allergies. Any allergy or dietary question should go straight to a human or to a clear, pre-approved answer.
• Feed it your real menu. Prices, modifiers, sold-out items and hours must stay in sync with your POS, or the bot will promise what the kitchen cannot make.
• Listen to recordings weekly for the first month. You will learn more from twenty calls than from any vendor dashboard.
• Track missed calls, order accuracy and complaints, before and after. If the numbers do not improve, turn it off.

Our view: AI ordering is worth testing for most busy independent restaurants, but as a backup, not a replacement. Use it to catch the calls you are already missing, keep humans on the front line for everyone who wants one, and remember that in this business the voice on the phone is part of the hospitality.
