On 29 April Ben Patterson, a journalist in New York, opened Claude and asked it to book dinner at The Smith on Second Avenue. The model surfaced live availability from Resy and offered a 7:15pm slot. He finished the booking inside the embedded Resy widget, and the integration American Express had announced six days earlier did its first work in print.
That integration, between Anthropic and Resy, lights up a new AI discovery surface for US restaurants on Resy.
A second booking surface, on different terms
Google AI Mode brought agentic restaurant booking to the UK and seven other markets on 10 April, wired into TheFork, OpenTable, SevenRooms, ResDiary, Mozrest, Foodhub, Dojo, and DesignMyNight. Resy was not on that list. The Claude-Resy integration runs the same play in the US, with one platform and one assistant.
The two surfaces do not share data. A restaurant on OpenTable in Manchester turns up in Google AI Mode and is absent from Claude. A restaurant on Resy in Manhattan turns up in Claude and is absent from Google AI Mode, which has not yet launched booking in the US. For a US operator choosing a reservation system this quarter, that asymmetry is now a discovery decision as well as a margin one.
The integration is real, and it's clunky
Patterson's test went through, but it was not seamless. Claude found The Smith, surfaced live availability, and then handed off — he had to tap the slot inside the Resy widget himself. Claude does the discovery; Resy still owns the transaction.
Claude can see which restaurants on Resy have a 7:15pm slot tonight. It cannot see anything about restaurants that aren't on Resy.
The hand-off is not the interesting part. The data behind Claude's answer is. To recommend The Smith to a diner asking for a casual American dinner in Midtown East, Claude needs to know what The Smith is, where it is, what it serves, how it is priced, and what kinds of party it does well. Some of that lives in Resy's own listings; the rest lives wherever the open web has indexed it.
Where the menu data goes
Resy holds the reservation inventory and a thin layer of venue facts: cuisine, neighbourhood, price band, opening hours. It does not hold the full menu in machine-readable form for most listings. When a diner asks Claude whether there is a vegan main at The Smith, or whether a coeliac can eat at Rosa Mexicano, the model falls back on whatever else it can find about those restaurants.
Being on Resy gets a restaurant onto the discovery shelf. The schema on its own site decides whether Claude can answer the next question accurately or politely declines.
What this means for operators
Three weeks ago, "be on the right reservation platform" was a narrow operational question. Fees, EPOS integrations, marketing reach. Now it is also a discovery question, because the platform an operator chooses determines which AI assistants can surface their restaurant.
The hedges are obvious enough.
A US restaurant on Resy gets the Claude shelf. One on OpenTable in the UK or Australia gets the Google AI Mode shelf. A restaurant that is on neither, or whose menu lives as a JPEG on Instagram, gets neither.
GMMO is one option for the underlying problem — keeping a restaurant's menu, hours, and dietary information in machine-readable form on a domain the operator owns. That does not substitute for being on the platforms, but it determines whether the AI making the recommendation can describe what arrives at the table.
The platforms are picking sides
Anthropic shipped fifteen everyday-app connectors on 24 April; Resy was the only US restaurant booking platform on the list. Google's AI Mode launch used a different eight platforms entirely. There is no shared registry. Each AI vendor is cutting bilateral deals with the booking systems it likes.
For diners that produces slightly different answers in different tools. For operators it means the floor plan of AI restaurant discovery is being drawn one partnership at a time, and being absent from a partnership is the cheapest way to be absent from a surface.
The booking widget loads. The 7:15pm slot is there. The next diner who asks Claude where to eat tonight will choose from a shortlist whose contents were decided last week in a press release.
