AI answering service for restaurants: hours, location, menu and dietary questions

What it is

An answering agent for a restaurant picks up the calls that are questions, not transactions: are you open now, are you open on the holiday, where are you, is there parking, do you have a kids' menu, is the curry spicy, is anything vegan, is the bread gluten free, do you take large groups, can I bring a cake. It answers from data you already maintain, resolves dates aloud when the question is about a day, and transfers or takes a message when the question is outside its data or the caller asks for a person. When the call turns into an order or a booking it either handles that too or routes it by your rules.

These calls are short, often under a minute, and they arrive in the same hour as the orders. They are also where a prompt-only agent embarrasses you: holiday hours from last year, a price from the old menu, or a cheerful "yes, that's gluten free" about a dish that is not. The fix is structural, not verbal. Hours from the profile you already update, the menu and prices from the POS, dietary flags from the same ingredient data the kitchen uses, and policies from one sheet.

Independents call this an AI answering service or AI receptionist. Groups call it front-of-house call deflection and measure it per venue.

Who buys it

• Independents and small groups whose staff answer the same twelve questions sixty times on a Saturday, and whose voicemail fills with "are you open?"
• Restaurant groups with central marketing that wants one accurate answer for hours, parking and policies across venues, and a transfer tree that lands on the right person at each site.
• Venues without an ordering or reservation integration yet, buying the questions layer first and adding orders and bookings later.

Budget owner: the owner or general manager; in groups, the marketing or operations lead, with whoever maintains hours and menu data owning the sources.

KPIs

Tag one week of calls by intent before you deploy; the share that are pure questions is the ceiling for this use case. Then track FAQ containment, answer correctness against your sources, allergen handling, transfer accuracy and answer rate during service.

The trap is correctness. Containment of 90 percent with wrong holiday hours in two percent of answers is worse than a transfer. Sample fifty transcripts a week against the sources, and treat any allergen guarantee as a defect regardless of how the call ended.

Demo script

Give the vendor your hours with one holiday exception, your POS menu with dietary flags, a policy sheet (cake, dogs, vouchers, corkage) and a transfer tree. Change one hour and one price mid-demo.

1. Greeting. Pass: restaurant name, AI disclosure, recording notice, "how can I help?"
2. Ambiguous date. Ask "are you open on the Monday?" when a holiday is ten days out. Pass: it names the date, reads the exception from the hours source, and offers the next open day if closed. Fail: it reads standard Monday hours.
3. Interruption. While it recites the address, cut in with "is there parking?" Pass: it stops and answers parking from the policy sheet.
4. Dietary question. Ask what is vegan on the menu. Pass: items read from dietary flags, with prices from the POS.
5. Allergy question. Ask whether the bread is safe for a coeliac. Pass: ingredients and your wording, no guarantee, offer to note it on a booking or transfer. Fail: "yes, it's gluten free, no problem."
6. Changed data. Have your administrator change a price and an opening hour in the sandbox, then ask again. Pass: the new values. Fail: the old ones.
7. Quantity-style change. Ask "a table for four tonight... actually six, around eight". Pass: it either books with the corrected size by your rules or transfers to bookings with the corrected size and time in the note.
8. Eight seconds of silence. Pass: one short prompt, then a graceful close with the option to call back.
9. Out-of-scope. Ask whether you can film a music video in the dining room. Pass: "I don't have that information", then a message for the manager. Fail: an improvised yes.
10. Transfer. Ask for the manager about an invoice. Pass: transfer to the configured destination with the question passed along, and a message taken if nobody answers.

Score each trap pass or fail. A wrong hour after the change in turn 6, or a guarantee in turn 5, is a hard stop.

Compliance notes

This is inbound and informational, and a call the customer places is outside the TCPA consent rule in the United States. Recording is the live question: roughly a dozen states require all-party consent, so announce it at the start. Several states have bot-disclosure laws, so disclose by default. On allergens, federal law defines nine major allergens, with sesame since 1 January 2023; the labelling rule does not cover restaurant food served to order, but a wrong spoken answer is still yours, so the agent reads data and never guarantees. If the agent offers to text the menu or directions, that is an outbound text and needs consent captured on the call. In the United Kingdom, food businesses must provide information on 14 allergens for non-prepacked food, and since 1 October 2021 prepacked-for-direct-sale items carry full ingredient labelling under Natasha's Law; recording is personal-data processing under UK GDPR, and any later marketing call needs specific prior consent under PECR Regulation 19. In the European Union, the AI Act's Article 50 duty to tell callers they are talking to an AI applies from 2 August 2026, and the 14-allergen duty applies. In Australia, state surveillance-devices laws differ, so announce recording; promotional callbacks sit inside the telemarketing hours of Monday to Friday 9 a.m. to 8 p.m. and Saturday 9 a.m. to 5 p.m. Informational, not legal advice; the compliance rows on this page carry the sources.

Build or buy

Buy, and buy cheaply; this is the starter use case and most ordering and reservation agents include it. The one thing to insist on is sources over prompts: hours from a profile you maintain, menu and prices from the POS, dietary flags from data, policies from one sheet you can edit. If a vendor's answer to "how do we change the holiday hours?" is "send us an email", keep looking. The acceptance test is turn 6 of the script: change a price and an hour, ask again, hear the new values.
