“Best restaurant chatbot” searches return seven tools that do four different jobs. This guide sorts them by the problem each one actually solves, with published starting prices, what each does with AI, and the limitation each vendor would rather you did not notice.
Disclosure: BuiltABot publishes this guide and is included in the comparison. We have marked it clearly, listed its limitations alongside everyone else's, and linked every competitor's own pricing page so you can check our claims. Where another tool is the better fit, we say so.
How We Compared (and Our Bias)
We build BuiltABot, so we have an obvious interest here. To keep this useful we applied the same four questions to every tool, including ours:
- What problem does it solve? Unanswered website questions, missed bookings, missed phone calls, or floor management are different problems with different tools.
- Does the AI answer from your content? A bot that quotes your allergen chart is useful; one that improvises is a liability.
- How does it book? Into your calendar, into a reservation platform, or not at all.
- What does it really cost? Entry price plus the per-cover, per-conversation or per-seat fees that appear on the second invoice.
Prices below are published starting prices as of the date shown; every price links to the vendor's own page.
The 7 Options at a Glance
1. BuiltABot (ours): website assistant that books into your calendar
Best for: independent restaurants and small groups that lose bookings and questions after the phone stops being answered.
BuiltABot crawls your website and ingests your menu and allergen PDFs, then answers guest questions from that content only, in the guest's language. When someone wants a table it shows real availability from Google Calendar, Cal.com or Calendly, books the slot, and sends confirmation and reminder emails. Private-event enquiries can be captured as leads and pushed to email or Slack; anything the bot should not decide (a party of 30, a buyout) escalates to staff.
Price: $29.99/month (1 agent, 2,500 messages, 25 documents, 50 pages). $79.99/month adds intake questionnaires and analytics. No per-cover or per-message fees. 14-day free trial, no card. Full limits on the fact sheet.
Limitations: it is not a reservation platform. No floor plan, waitlist, table-turn management or POS integration, and it does not sync with OpenTable, Resy or Tock. It does not answer phone calls. If you need those, pair it with one of the tools below.
2. Tidio: live chat inbox with an AI add-on
Best for: restaurants that want staff to chat live from a shared inbox and are happy to pay for AI per conversation.
Tidio is a mature live-chat product with a large template library and marketing pop-ups. Its Lyro AI answers from your FAQ content. The trade-off is pricing: the plan covers the inbox, and AI conversations above the included allowance are billed separately, so a busy weekend can move the bill. There is no native calendar booking; you link to a booking page.
Limitations: per-conversation AI cost; no booking engine; the richest features sit in the higher tiers.
3. OpenTable: the reservation network
Best for: rooms that fill from marketplace discovery and need real floor management.
OpenTable is not a chatbot and does not pretend to be one. You pay for diners it brings (per-cover fees on network bookings) and for the operations layer: floor plans, waitlist, turn times, guest profiles. If a large share of your covers come from people browsing OpenTable, the fees are the cost of that channel.
Limitations: does not answer guest questions on your website; cover fees scale with success; you share the guest relationship with the platform.
4. Resy OS: premium reservations, flat fee
Best for: destination restaurants in major cities that want a reservation platform without per-cover fees.
Resy charges a flat monthly fee and is strong on ticketed events and waitlists. Its diner network is concentrated in larger cities. Like OpenTable it does not answer questions on your site.
Limitations: higher entry price than any website assistant; no AI Q&A; network thinner outside metro areas.
Best for: restaurants that want to replace their website, add online ordering and get AI answering from a single vendor.
Popmenu bundles a restaurant website, menu management, ordering and an AI answering layer for phone and web. The appeal is one vendor; the cost is that you move your site onto their platform, and pricing is quote-based rather than published.
Limitations: platform lock-in; no published pricing; overkill if your website is fine and you only need chat and booking.
6. Slang.ai: AI that answers the phone
Best for: restaurants where the phone, not the website, is the leak.
Slang.ai answers calls with a voice AI, handles hours and reservation questions and can book into supported reservation systems. It is a different channel from everything else here and can run alongside a website assistant.
Limitations: phone only; starting price is higher than website tools; depends on your reservation system for bookings.
7. Tawk.to: free human live chat
Best for: restaurants that want a chat bubble for free and have someone to answer it.
Tawk.to is genuinely free for live chat. The catch is in the name: it is live. If nobody is online at 10pm the visitor gets an offline form. AI answering is a paid add-on and does not book tables.
Limitations: no booking; AI is basic; value depends on staff availability.

Which One Should You Pick?
- Website questions and after-hours bookings, flat price: BuiltABot. Tidio if you prefer a live-chat inbox and accept per-conversation AI fees.
- Discovery and floor management for a busy room: OpenTable (network reach) or Resy (flat fee, premium brand).
- Missed phone calls: Slang.ai, possibly alongside a website assistant.
- New website plus ordering plus AI in one contract: Popmenu.
- Zero budget and staff online: Tawk.to.
A common, sensible stack for an independent: a reservation platform if discovery matters, a website assistant like BuiltABot for questions and direct bookings, and phone AI only if call volume justifies it. See the restaurant solutions page for setup details, or the reservation-bot integration guide for a step-by-step.
What is the best AI chatbot for a restaurant website?
For most independent restaurants the best fit is a flat-price website assistant that answers menu, hours, allergen and private-event questions from your own content and books tables into your calendar after hours. BuiltABot (ours) does exactly that from $29.99/month; Tidio is the main alternative if you also want a live-chat inbox and are comfortable with per-conversation AI fees. If your bottleneck is table management or discovery, OpenTable or Resy are the right category instead.
Does a restaurant chatbot replace OpenTable or Resy?
No. Reservation platforms manage your floor plan, waitlist and turn times and bring diners from their marketplace. A website chatbot converts visitors already on your site and answers their questions. Many restaurants run both: the platform for discovery and seating, the chatbot for guest questions and direct bookings. BuiltABot does not sync with OpenTable, Resy or Tock; it books into Google Calendar, Cal.com or Calendly.
How much does a restaurant chatbot cost in 2026?
Website chat assistants run $0 (Tawk.to, no AI) to roughly $30–$150 per month. BuiltABot is $29.99/month for one agent and 2,500 messages, $79.99 for five agents and 15,000 messages. Reservation platforms cost more: OpenTable from $149/month plus per-cover fees, Resy OS from $249/month. AI phone answering (Slang.ai) starts around $199/month. Prices are as published on vendor pages when we checked; confirm before buying.
Can a chatbot answer allergen and dietary questions safely?
It can answer from the allergen chart and menu you upload, and it should say so: a good restaurant bot tells guests it is quoting your published allergen information and to confirm with staff for severe allergies. BuiltABot only answers from your content and declines when the information is not there, which is the behaviour you want for this class of question.
Do I need a chatbot if I already have Slang.ai or another phone AI?
They solve different problems. Phone AI stops missed calls; a website chatbot stops missed website visitors, who outnumber callers for most restaurants. If you can only afford one, look at where your after-hours demand actually arrives: phone logs versus website analytics.
How long does it take to set up?
Website assistants take an afternoon: upload the menu, let the tool crawl your site, connect a calendar, paste one script tag. BuiltABot setups typically take under an hour. Reservation platforms take days to weeks because of floor-plan configuration and POS integration.
