It is half past eight on a Friday. The dining room is full, the kitchen is loud, and the phone rings. You pick up, and a calm voice asks how long the wait is for a table for four. You say forty minutes. The voice says thanks and hangs up. Somewhere, a person got a text message with your answer and decided whether to come.
That caller may not have been a person at all.
What changed this week
On 20 October, TechCrunch reported that Yelp is rolling out a feature called "Check for Me". On a restaurant's page in the app, a customer enters a party size and a phone number. A voice AI then calls the restaurant to ask about the wait and texts the answer back. The same report says Yelp already offers restaurants their own voice agent, launched in 2025, and notes that the two could end up talking to each other.
Two things the report does not say: whether the caller tells you it is an AI, and whether a restaurant can opt out. Nor does it say where the feature is available. So I will not tell you what it does in your town. I can tell you what to get ready for.
Why this is a different kind of call
An ordinary customer phones once, and it costs you thirty seconds. An assistant that phones on behalf of many people is a new sort of caller. It never gets bored, it does not mind being put on hold, and it asks the same narrow question: how long is the wait?
That sounds harmless, and mostly it is. A person who gets a straight answer comes in knowing what to expect. A person who cannot get through may go next door.
The risk is the wrong answer, not the extra call. Forty minutes is a guess. If your host says "about forty" over the noise and the assistant relays "forty minutes, guaranteed", someone arrives with a promise you never made. The honest fix is boring: say the number as a range, and say it the same way every time.
The other side of the phone: your own AI
The same TechCrunch report points out that a restaurant's voice agent could answer these calls. This is where it gets interesting for you. If you ever put an AI on your phone line, it will increasingly be talking to other AIs, with no human on either end, and that is when small misunderstandings pile up.
What matters then is not how clever the agent is. It is what it is allowed to do. The 2025 launch report says Yelp's agent hands more complex requests to a human, and sends the business a summary, a transcript and the recording after each call. That is the right shape, and it is the one to look for in any tool: a short list of things it may do alone, a clear handover for everything else, and a record you can read in the morning.
For a wait-time question, "alone" is fine. For a booking for twelve with a nut allergy, a person should call back. I wrote about the same line for orders in Can an AI Order From Your Restaurant Now? and for chat in Should You Let AI Answer Your WhatsApp Business?.
What I have not verified
The Check for Me report is one news article with no quotes from Yelp or from any restaurant. What I know about Yelp's restaurant agent comes from Yelp's own 2025 announcement as the press relayed it, and I found no independent testing of how accurate its wait estimates are. And this is Yelp. Other apps are building similar callers, so the better question is not "which app" but "what do I do when a machine rings me".
It may also never reach you. Your guests may not use these apps at all. In that case you have lost nothing by thinking it through.
One thing to do this week
Pick the three questions your phone gets most (wait time, opening hours, can you take a group). Write one plain answer for each, on a card by the phone. Add one rule: anything involving allergies, money or more than six people gets a callback from a human.
Then the card does two jobs. It makes your staff consistent today, and if an AI answers your phone one day, it is already the instruction sheet.
