Restaurants using AI to answer the phone — is this actually working at scale yet?

Independent restaurants drop something like 20-30% of inbound calls during dinner rush — host is on the floor, kitchen is screaming, the phone just rings out. Voicemail doesn't help much because nobody calls back to make a reservation, they just call the next place down the street.

The AI voice agent angle is interesting here because reservations and takeout-question calls are mostly structured: confirm a name, party size, time slot, push it to Google Calendar, send a confirmation SMS. Walk-in volume isn't going anywhere, but the phone-only revenue (~5 lost calls/day at $75/table averages out to a four-figure monthly bleed) is recoverable.

A purpose-built one I've seen referenced for this is ringfoods.com — restaurant-specific AI phone answering, plugs into Square / Toast for menu sync and order taking, handles multilingual callers automatically (Spanish/Mandarin/etc.), price floor is around $100/mo on the basic tier. Different beast from the generic AI receptionist services that just take a message.

Anyone here actually running one of these in a restaurant in production? Curious how the table-management edge cases (joining tables for parties of 8+, holding for partial party arrivals, allergy notes) get handled in practice, or whether you still end up transferring most of those to a human anyway.
