An AI assistant for your restaurant: who answers, and who books

When a restaurant owner asks about “an AI assistant”, they usually mean one of two things.

One answers your phone when you’re too busy to. The other belongs to your guest: the ChatGPT or Gemini they ask to “find us a table for four on Saturday”. Both are in the dining room now, and they need different things from you.

The one that answers your phone

AI phone answering is the better known of the two. It picks up when the line is busy or the restaurant is closed. It answers the questions you hear fifty times a week: are you open on Monday, is there parking, can you do a birthday cake. It takes a booking, and hands the call to a person when it should.

It’s no longer a fringe tool. OpenTable says it works with more than 20 voice AI partners, which had seated 3 million diners by August 2026. The diners they seated in 2026 were up 270% on the same period of 2025.

Before you choose one, ask:

• Does it write into the book you already use? A voice assistant with its own diary will sell the same table twice. It should book into your reservation system, the one your hosts look at.
• When does it hand over? A party of fourteen, a complaint, a guest with a serious allergy: those should reach a person, not a script.
• What does it say about allergens? It should never guess. “Let me check with the kitchen” is the only safe answer it can give on its own.
• Does it say it’s an AI? Callers should know who they’re talking to. In the EU, the AI Act requires it of AI that talks to people, from August 2026.

The one your guest brings

The bigger change this year is on the other side of the call. Guests now ask their own assistant to find and book a table, and the big assistants do it through the booking platforms they work with:

• ChatGPT finds free tables and books them through OpenTable worldwide, Resy in the US and Yelp in the US and Canada, since 10 August 2026 (report).
• Google’s AI Mode finds restaurants with free tables and links to the booking platform to finish, in the US and, since April 2026, Australia, Canada, Hong Kong, India, New Zealand, Singapore, South Africa and the UK.
• Gemini can reserve a table with OpenTable in the UK, through apps it connected in August 2026.
• Claude shows Resy restaurants in the US with their free tables, since April 2026, and the booking finishes on Resy.

It’s already moving covers. In its August announcement, OpenTable said its links with AI assistants, Google’s, ChatGPT, Copilot and Perplexity among them, seated 17 times more diners than a year before. Some of those diners spent 20% more on average than diners from other channels.

If you’re on a booking platform

Then guests’ assistants can probably book you already. A few things are worth a look:

• Your listing’s words. The assistant reads your platform page and your own site. Put the menu, with prices, on both, as text rather than a photo.
• How many covers you release online. The assistant can only book what the platform shows as free.
• Which assistants your platform works with, and where. OpenTable, Resy and Yelp are not in every country, and neither is each assistant’s link to them.
• What it costs you. Each platform has its own fees. Ask whether a booking from an assistant is charged like any other.

If you’re not

Many independent restaurants aren’t on any platform. They take bookings by phone, by email, through Instagram or WhatsApp messages, or through a form that says “we’ll confirm shortly”.

A guest’s assistant can’t use any of those tonight. It isn’t rude about it. It simply books the place next door that answered. We wrote about how that looks with OpenAI’s dots: three restaurants on one street, and the booking goes to the one that could say yes.

Here’s what an assistant needs to book you directly:

1. Your menu and prices, written down. As text on your own site, with what’s in each dish if you can.
2. Real free times. “Is Saturday at 8 free for four?” needs a live answer, not a picture of your opening hours.
3. A door it can use. A booking page that confirms on the spot, or an MCP server, the standard way assistants plug into a service. An email address is a queue, not a door.
4. Your rules, answering for you. A table for two when there’s room can confirm itself. A party of twelve, or a request for the whole room, should wait for you.
5. A deposit where you need one. For big groups, or the nights you lose most to no-shows.

Very few businesses have this yet. On 28 October 2026, of the 2,570,532 business websites our crawler had checked, 66 could take a booking through a door an agent could use.

Surfing Dog Inbox is our way to give a restaurant that door, on its own domain. It’s open source, and we can host it for free. It keeps its own book, so you set aside the covers it may book for each service, such as dinner. A party that fits in what’s left of them, in a free sitting, is confirmed at once. Larger ones come to you, and you seat them from the whole room. You can ask for a deposit per person from a party size. It takes orders for collection or delivery too, at times your kitchen can make, and can start from your menu in GloriaFood or Flipdish. It never guesses an allergen: until you or your staff confirm a dish’s allergens, assistants are told to ask you. Restaurants, bakeries and cafés has the details.

Both at once

The phone assistant and the guest’s assistant meet in one place: your book. Whichever AI takes the booking, phone, platform or your own door, your hosts should see it in the list they work from. Where two systems each take bookings, give each its own covers, so a table is never sold twice and nobody has to copy anything across at nine on a Saturday.
