FAQ

Restaurant Voice AI, answered

Voice AI is an AI phone answering system built for restaurants. It picks up calls, answers common guest questions, and books reservations directly into your system, with no hold time. SevenRooms Voice AI works alongside your team, so staff spend less time on the phone and more time with guests in the room.

It depends on your call volume, party size, and average spend — which is exactly what this calculator estimates. As a benchmark: at the industry average of 65 calls per day, a restaurant missing 40% of calls could be losing tens of thousands of dollars in reservation revenue every year. Enter your own numbers above to see your figure.

We take your daily call volume, multiply by the share of calls that go unanswered, and assume 36% of missed calls are new booking requests, based on calls answered by SevenRooms Voice AI. Each missed reservation is then valued at your average party size times your average spend per guest, annualized over the year.

Yes. Voice AI answers calls in a natural voice, handles questions about hours, menus, and policies, and books reservations straight into your system — no callbacks, no voicemail. Most diners say they're open to booking by AI phone call.

The traditional options are hiring more front-of-house staff or a call center, and both are expensive. An AI phone answering system is the most cost-effective fix: it answers calls instantly, including during peak service and after hours, when most missed calls happen.

*SevenRooms US Research is based on data in the 2026 US data report.

Revenue estimates are for illustration only, are not a forecast or guarantee, and are based solely on the figures you provide and assume 365 operating days per year. We estimate that 36% of missed calls are new booking requests, based on 400K+ calls answered by SevenRooms Voice AI between 1 July and 30 September 2026 (excluding spam and non-guest calls). Each missed booking is valued at your average party size multiplied by your average spend per guest. Actual results will vary by venue, and depend upon several variables and factors specific to and impacting the venue. SevenRooms does not guarantee that Voice AI will answer all calls or recover any particular amount of revenue.
