What is the best AI voice agent for restaurants in 2026?

Fonio is the most complete ready-made option we found. It has a dedicated restaurant product that covers both jobs the phone does: reservations, with a live check on open tables, and takeout or phone orders, sent to the kitchen or the POS. In between, the agent clears the calls that clog the line: hours, menu, prices, allergens, parking. It passes along what it shouldn't handle, such as a complaint, a catering request or a party of twenty.

Pricing is built around call volume. Solo is €119 a month, or €99 billed annually, for 1,000 minutes and up to 20 calls a day. Team is €359 (€299 annually) for 3,600 minutes, up to 100 calls a day and three calls at once. Scale is custom above that. A restaurant taking 400 two-minute calls a month fits inside Solo on paper. The vendor's examples show English, French, German and Dutch.

The catch: Fonio talks about connecting to your reservation software, your POS and your kitchen display, but names none of them. Not OpenTable, not Toast. Ask for a demo where the agent books a real table in your real book. Solo can't take two calls at once, so on a Friday at 7:30 p.m. the second caller waits. There's no free trial listed, only a 30-day money-back guarantee, and prices are in euros, excluding VAT. Restaurant reviewers praise fewer missed calls during the rush; reviewers in other industries mention heavy accents and specialist terms that don't transcribe well, which can hit dish names.

Tip: load your menu in the knowledge base the way guests say it out loud ("the four-cheese", not "PZ-4F"), with one line per major allergen. The agent answers better and hands off when it isn't sure.

ElevenLabs is best known for synthetic voices, and it's also the engine behind SevenRooms Voice AI. That agent books tables in real time inside SevenRooms, follows the venue's rules (time slots, party size, deposits, notes), recognizes returning guests and hands off to staff. The two companies report 600+ restaurants using it, 400,000+ calls handled, and roughly one call in five coming in after hours.

Outside SevenRooms, you can build your own agent on ElevenLabs Agents. Plans run from $0 for 15 minutes to $99 a month for 1,238 minutes, with extra minutes at $0.08. ElevenLabs doesn't charge for telephony: if you connect a Twilio number, Twilio bills you directly. The language model is billed on top, depending on which one you pick.

The catch: outside SevenRooms, nothing is pre-built for restaurants. Someone has to write the call flow, connect the book over the API and run test calls. SevenRooms doesn't publish the price or the languages of its voice agent, so ask them. Our full ElevenLabs review gives it 4.2 out of 5 with support at 3.4: public reviews mention billing complaints and credits burning faster than expected.

Tip: if an integrator builds it, have them cap call length and pick a fast model. On the phone, an instant answer beats a clever one, and a takeout order rarely runs past four minutes.

Zenchef is a restaurant reservation platform based in Europe, with self-serve activation of its agent in France and Belgium. Call AI, its voice agent, picks up around the clock, uses your restaurant's information and writes the booking straight into Zenchef. That's the whole point: no integration to build, no double entry, and the slots offered on the phone follow the same availability rules as your website.

According to the vendor's documentation, it's an add-on to your Zenchef plan. You get a dedicated number and forward your public line to it. When a slot needs a card hold or a deposit, the agent texts a payment link instead of taking card details by voice. When you're full, it offers other times or transfers the call. One Zenchef customer says 30% of its calls are booking changes, which shows how much phone time is at stake.

The catch: when we compared, the vendor's help docs said the agent couldn't yet modify or cancel a booking, and offered one default voice. Check both in a demo, because changes are a big share of calls. Zenchef lists €99 a month with no detail on tax or locations, so confirm what it covers before you sign. It doesn't take takeout orders: it's a booking tool.

Tip: keep your existing number on Google and your website, and forward it to Call AI only after four rings and outside service hours. Regulars still reach your team; the agent catches the rest.

Slang AI is the best-known US specialist for restaurant phones. Its sweet spot is reservations and events: it connects to OpenTable, SevenRooms, Yelp and Resy for tables, and to Tripleseat and Perfect Venue for private dining. The vendor promises setup in under 30 minutes and lists no cap on calls.

Pricing is per location: Core from $399 a month, Premium from $599, Enterprise custom. Spanish is included in Core, which matters in plenty of US markets. Premium adds 97 languages with automatic detection and mid-call switching. A 14-location group quoted in the trade press pays about $450 per location per month, and says it freed its hosts from the phone at a site that took 250 calls a week.

The catch: it's priced for groups and high-end rooms, and that's the main criticism in the press. Its pricing page doesn't put takeout ordering front and center, so check that in a demo if pickup is your main revenue. Independent reviews are almost nonexistent: one review on a major review site when we compared. You're buying on the vendor's word and references.

Tip: if you have a private dining room, look hard at the Tripleseat or Perfect Venue connection. Event inquiries often come in by phone, and that's where a specialist agent earns the most per call.

Retell AI is a platform for building your own voice agent, and one of the few that publishes a full restaurant page. It covers takeout and delivery orders with menu modifiers, bookings with text confirmation, changes and cancellations, allergen questions, batch reminder calls, handoff with a call transcript, payment by text link and multi-location setups.

The integrations are the real difference: Toast, Square and Clover on the POS side, OpenTable and Resy for reservations, plus Zapier, Make, n8n, Twilio and Cal.com. Pricing is per minute, from $0.07 to $0.31 depending on the LLM and voice, with 20 concurrent calls included. During the Friday rush, nobody hears a busy signal.

The catch: nothing works until someone builds it. Public reviews describe 1.5 to 2.5 seconds of latency with some models (a silence callers notice). The restaurant page doesn't list languages, and the real per-minute cost depends on the model and voice you pick.

Tip: have the agent read every order back, modifiers included, before confirming, then text a summary. That's the best guard against wrong orders, the most common diner complaint about phone AI.
