QR Menus, Kiosks and Robots: Where Technology Helps and Where It Hurts

Restaurant technology helps when it takes over a transaction the guest never wanted to have, and hurts when it takes over a moment where the guest wanted to be noticed. QR menus, kiosks and robots each sit on one side of that line, depending on what kind of restaurant you run.

Picture two guests. One stands in a quick-service queue and wants a burger in four minutes. The other has booked a table for an anniversary. Both meet a screen. The first is relieved. The second feels she has been handed a form. The technology is the same. The task is different.

What is the one test for any restaurant technology?

Ask what the guest is trying to do at that moment, and whether they want a person involved. A transaction is something to finish: order, pay, split a bill, find the toilets. A moment is something to feel: being greeted, being advised, being forgiven after a mistake.

Technology earns its place in the first category. In the second, it needs to be invisible or absent. Failures often come from using a transaction tool on a moment.

Do guests actually like QR code menus?

In table service, mostly not. A blind survey fielded on 16 September 2024 by Toast, of 850 US adults who had dined out in the previous 90 days, found 81% preferred a physical menu and 1% preferred QR codes. Among guests aged 55 and over, the physical menu preference rose to 90%.

The complaints were practical. Of respondents, 26% named small text on a phone as their main dislike, 20% disliked having to use their phone at all, and 16% pointed to unreliable technology. It is one US survey from a company that sells restaurant software, so read it as a signal, not a universal rule. Still, 17% did say they liked that QR menus avoid dirty menus, which is a fair point and a reason to keep both formats.

The lesson is to keep QR codes, as a fallback and a channel for updates rather than the only way in. A paper menu on the table costs little and respects the guest who is there to be looked after.

Where do kiosks help?

Kiosks help in quick service, where the order is simple, repeated and judged on speed. A 2025 report from Tillster, summarised by Restaurant Dive, found that 61% of 1,500 US quick-service and fast-casual consumers wanted more kiosks, up from 36% in 2023. Respondents cited accuracy, convenience, speed and customisation.

Two cautions. The article does not describe how respondents were recruited, and the report is from a kiosk company, so the figures are indicative only. And one of its findings deserves a second look: 76% of kiosk users said they had occasionally bought more than they planned. That is good for the till. Whether it is good for the guest is a question each operator should answer honestly.

A kiosk shifts work as well as saving it. Someone must keep the menu data right, clear the screen of errors and help the guest who is stuck. Count that labour before you count the saving.

What about robots?

Robots help with carrying and clearing, and the guest-facing case rests heavily on novelty. A 2023 study in Cogent Business & Management, using survey data on robot-staffed restaurants, found that perceived enjoyment, speed and novelty raised satisfaction. Perceived usefulness did not. The page does not report the sample size, so the study is hard to weigh.

If novelty is doing the work, the effect should fade for a local regular. A robot that brings dishes from the pass to the table can give a server another minute with each guest. A robot that is the main attraction is a novelty with a maintenance contract.

The better question is where in the room it lets people do human work. That ties back to how well your kitchen communicates at the pass: a robot cannot fix a slow handover upstream.

How do the three compare?

None of these suits the moments that make a table memorable. Those are the seven moments of a guest experience, and many of them involve a person.

If you keep a QR menu, what should you fix first?

Fix legibility, scanning and explanation, in that order. The same Toast write-up recommends optimising the online menu for mobile, printing codes large enough to scan, testing them regularly, and training servers to explain the process. Those are small jobs, and they answer the complaints guests actually gave.

A short routine helps:

• Open your own menu on an older phone, in a dim room, on the venue's weak wifi.
• Check that the text is readable without zooming and the allergen information is easy to find.
• Have the server say one sentence when greeting: how to scan, and that a paper menu is available.
• Review the code and the page monthly, and after every menu change.

Imagine a 50-seat wine bar that moves to QR menus to save printing costs. The saving is real, but guests aged 55 and over, who in the survey above leaned most heavily towards paper, may be the ones booking the early table. If a server must keep fetching paper menus anyway, the venue has added a step instead of removing one.

A decision rule for the next tool

Before you buy, answer four questions in writing:

1. Which task does this remove, and who does it today?
2. Does the guest want to be seen during that task?
3. What new work does it create, and who will do it?
4. What is the fallback when it fails on a Saturday night?

If the answer to the second question is yes, the tool should assist a person, not replace one. If the fourth answer is "we don't have one", wait. The same discipline applies when you choose a POS system: the checklist matters more than the demo.

Technology should take the paperwork out of hospitality, and leave the welcome where it is.

Common mistake: measuring the saving, not the guest

Operators often count labour saved and miss what guests quietly lose. The fix is cheap. After a trial of four to six weeks, compare repeat visits, review comments that mention staff, and spend per head. Ask the team what guests said at the table. If reviews begin to say "impersonal", you have your answer, whatever the spreadsheet says.

Key takeaways

• Sort every tool into transaction or moment, and use technology mainly for transactions.
• At table-service restaurants, offer a paper menu next to the QR code; one 2024 US survey found 81% of diners preferred paper.
• Kiosks suit simple, repeat orders in quick service, but they move labour rather than remove it.
• Robots are best judged as logistics help; do not count novelty as a lasting benefit.
• Write down the fallback before you buy.
• Measure repeat visits and guest comments, not only labour hours saved.
