AI in restaurant systems: value for owners, staff and guests

AI adds value when it makes a task easier to complete. A fast chat is insufficient if its answers lack the right source information. Evaluate the feature through work someone actually needs to do.

For owners: a question with checkable evidence

A useful question might be: “Which days last week had the lowest sales excluding VAT?” The answer should show the period and figures so they can be checked against the report.

Interpretation comes next. Were sales lower because of shorter opening hours, fewer guests or a lower average bill? AI can help organise the questions, but a possible explanation is not a proven cause.

Schedule proposals also need checking against availability, skills and applicable rules. A proposal supports a decision; it does not guarantee correct staffing or payroll handling.

For staff: information during service

Staff may benefit from help finding menu information or understanding a task. Test a specific modifier and a question about handling an order.

Check what the assistant does when information is missing. It should make uncertainty visible rather than fill in details. Allergens and possible adjustments must be confirmed under kitchen procedures. Previous orders do not establish current physical stock.

Train staff in both the feature and its limits. An easy interface does not replace knowledge of the menu, payments and exception handling.

For guests: understandable help

A digital assistant can help guests find information and proceed with ordering. Guests also need access to staff and an opportunity to check items, prices and choices before confirming.

QR ordering and mobile payment can be useful without AI. Assess them as separate functions. Opening a menu through a QR code does not establish how a language model is used.

Test quality as well as speed

Choose recurring questions with known answers and some where information is missing. Check permissions: a guest should not gain access to staff information or internal reports.

Language models can produce confident but incorrect answers, as discussed in NIST’s generative AI profile. Include review and corrections when measuring time saved.

Vendion has three AI agents for owners, staff and guests. AI is included in the platform. See Vendion live with a task for each role and assess the results together.
