One Restaurant Group 'Practically Retired Its Phones' After Deploying Voice AI

Casper Hospitality’s four U.S. locations “practically retired our phones” after switching to SevenRooms Voice AI, according to COO David Chen — the system handled more than 3,800 calls in one month, created over 850 covers, and generated $28,000 in booked revenue, without a host physically answering. SevenRooms frames the deployment as one entry point in a broader agentic shift already live in restaurant operations: a seating algorithm evaluating more than 10,000 table combinations per second against historical demand and party composition, AI-drafted responses to guest emails and reviews written in a restaurant’s brand voice, and an AI Feedback Summary tool that surfaces recurring sentiment patterns across hundreds of reviews without being told what to look for. The company’s stated recommendation for operators is incremental: start with the single highest-cost friction point rather than replacing the whole tech stack, and prioritize tools that enhance staff rather than replace them.

The gap Casper’s numbers close is one SevenRooms already quantified separately: 64% of diners still prefer to book by phone, but 40% of those calls go unanswered, even though 75% of diners say they’re comfortable booking via AI. Only 28% of operators had deployed reservation AI as of that report — meaning most of the restaurant industry is still leaving the majority of a preferred booking channel unstaffed rather than automated.

It’s vendor content — SevenRooms is naming its own products throughout — but a named operator with a specific call volume and dollar figure is a different order of evidence than a roadmap slide. For restaurant groups still treating phone coverage as a staffing problem rather than a routing problem, Casper’s month of data is a concrete number to hold a pilot against, not just another AI vendor’s pitch deck.
