What an AI receptionist for restaurants does during a busy service

What does an AI receptionist do on a restaurant call?

Think of it as a voice assistant on your restaurant line. It knows your menu, hours and booking rules, and it can act in the systems you connect it to.

Most restaurant calls fall into a few groups:

• Reservations: It asks for the date, time and party size, checks your booking system and books the table.
• Changes and cancellations: It finds the booking and moves or cancels it.
• Takeout orders: It reads back the order, handles changes like "no onions" and sends the order to your POS. A POS is the point of sale system you use to ring up orders.
• Hours and directions: It answers questions about hours, parking, patio seating and holiday times.
• Menu questions: It explains dishes and what is on special that night.
• Handoffs: It passes large parties, private events, complaints and allergy questions to a person.

Here is a simple example. A caller asks for a table for four at 7:30 tonight. The AI sees that 7:30 is full and offers 7:00 or 8:15. The caller takes 8:15, and the AI books it and texts a confirmation.

Keep allergies with your staff

Allergy questions need a person who knows your kitchen. Set the AI to pass every allergy question to a manager or take a callback number. A wrong answer here can hurt a guest.

Keep card numbers off the call

Do not let the AI ask callers to read out card numbers. Set it to text a secure payment link instead, or let guests pay at pickup. That keeps card data out of call recordings.

How does an AI receptionist work with OpenTable, Resy, Toast and Square?

The AI is only useful if it can see your tables and send orders to your kitchen. Here is what each company's own pages showed as of October 2026.

System	What it does	Price on its site	AI phone options
OpenTable	Reservations	Basic $149 a month, Core $299, Pro $499, plus cover fees	Works with outside AI phone tools such as Slang.ai
Resy (ResyOS)	Reservations and waitlist	From $189 a month, with no per-cover fee	Works with outside AI phone tools such as Slang.ai
Toast	POS and online ordering	From $0 a month, plus hardware and processing	Partner voice tools, such as SoundHound and Incept AI, send phone orders into Toast
Square for Restaurants	POS and online ordering	Free, Plus $69 a month, Premium $165 a month, per location	Square's own AI voice ordering, announced in October 2025

OpenTable

OpenTable charges a cover fee for each seated diner who books through its network. Basic plans pay $1.50 per cover after 30 days, and Core and Pro pay $1. OpenTable says phone bookings and walk-ins carry no cover fee. Its standard contract runs for one year and renews each year unless you give 30 days' notice.

Resy

ResyOS says it does not charge per cover. Its real-time POS integration costs $100 a month as an add-on. Its feature list includes API access. An API is a way for two pieces of software to share data.

Toast

Toast lists voice ordering tools in its partner directory. SoundHound answers calls, takes orders, answers common questions and sends orders into Toast. Incept AI loads your Toast menu and sends each phone order to the POS and kitchen screens. Neither partner page listed a price.

Square

In October 2025, Square announced AI voice ordering for restaurants. Square says it answers every incoming call and sends confirmed orders straight to the kitchen or POS. Its restaurant pricing page does not list the feature, so ask Square whether your plan includes it and what it costs.

What do AI receptionists for restaurants cost?

Restaurant phone tools usually price by location. Slang.ai lists its Core plan from $399 per location and its Premium plan from $599. It says it works with OpenTable, SevenRooms, Yelp and Resy. It also says it handles reservations from start to finish, texts guests ordering links and sends unknown questions to a person.

Compare that with a human service. Ruby, a US answering service staffed by people, charges $395 a month for 100 minutes and $720 a month for 200 minutes.

If you already use Square, ask Square about its voice ordering on your plan. Do that before you sign up for a separate tool.

Do restaurants need a chatbot too?

A chatbot answers typed questions on your website, Google profile or Instagram. It can share your hours, link to your booking page and answer menu questions. Many reservation tools already give you a booking widget for your site.

The best setup uses one source of facts for both the phone AI and the chatbot. Then your hours and holiday times only change in one place. My guide to AI chatbot development services explains how a custom chatbot is built.

What rules apply to restaurant phone AI?

Call recording

Many phone AI tools record calls to make transcripts. Federal law allows recording when one person on the call agrees. Several states, including California, Florida, Illinois, Pennsylvania and Washington, need all parties to agree. Start each call with a short line that says it is an AI assistant and the call may be recorded.

Calls and texts you send out

Inbound calls are simple. Outbound calls and texts need more care. The FCC ruled on 8 February 2024 that AI voices count as "artificial" voices under the Telephone Consumer Protection Act. That means you need a guest's prior express written consent before an AI calls them with promotions.

Texts that promote specials or events are marketing. Get written consent before you send them from an automated system. Guests can opt out by replying "stop", and federal rules give you 10 business days at most to honor it. Order and booking confirmations are a different kind of message from promotions.

What mistakes do restaurants make when they set this up?

Most of the problems I see are not the AI's fault, they are the setup. A few mistakes show up again and again.

• Letting it take allergy questions. This is worth repeating as its own point. A wrong answer on an allergy can hurt a guest. Every allergy question should go straight to a person who actually knows the kitchen, no exceptions.
• No cap on party size it can book alone. A 20-top needs a manager's judgment on timing and seating, not an AI quietly confirming it. Set a hard limit on what it can book without a human checking first.
• Only testing it during a quiet hour. The real test is whether it holds up when three lines ring at once during the Friday dinner rush, the exact moment it is supposed to help. A calm test call tells you very little.
• Letting it take card numbers out loud. Worth repeating here too, since it is an easy thing to miss in setup. Send a secure payment link or let guests pay at pickup, never have the AI ask a caller to read out a card number.
• Letting the menu drift out of sync. If a dish sells out and the AI does not know, it will happily take an order for something your kitchen cannot make tonight. Whatever updates your 86 list should also update what the AI can offer.

How do you set up an AI receptionist for a restaurant?

1. Write a fact sheet: List hours, holiday hours, parking, dress code, patio rules and the largest party you book by phone.
2. Load the menu with prices and options: Include sizes, add-ons and items that run out.
3. Set booking limits: Decide the largest party the AI can book and when it must pass the call to a manager.
4. Connect your systems: Link the AI to your reservation system and your POS, then place test orders.
5. Test during a quiet hour: Have staff call with hard requests, such as split orders or a birthday cake drop-off.
6. Review calls each week: Read the transcripts and fix any wrong answers.

When should a restaurant build a custom AI receptionist?

I build AI receptionists that connect to the POS and reservation systems a restaurant already uses. I start by listening to real calls, then build only what the ready-made tools miss. The restaurant owns the code and the accounts. If a ready-made tool already covers what you need, I will tell you. If you are still choosing a POS, my Toast vs Square comparison can help.
