Slang AI review: an AI host for restaurant reservations

Slang AI is an AI phone host for full-service restaurants. It answers the phone around the clock, answers the questions your staff hear fifty times a night (hours, parking, dress code, the patio), and books, changes and cancels reservations directly in OpenTable, SevenRooms, Resy or Yelp (Slang AI).

It is built around tables, not takeout. If most of your calls are orders, this isn’t the tool; if most are “do you have a table for four at 7:30 on Saturday”, it is squarely aimed at you.

Who it’s for

Slang fits sit-down restaurants where the host stand juggles the phone, the door and the waitlist at the same time, and restaurant groups that want callers steered to a sister location when one is full. It also captures private-event inquiries and sends them to Tripleseat or Perfect Venue (listed under Premium on the pricing page), which matters if events are a real part of your revenue.

It fits poorly if you need phone orders and payments to land in your POS. Slang lists no POS integration. For that, look at Loman, which takes orders with modifiers and payment into Toast, Square, Clover and others.

What callers hear

The AI answers, handles the booking or question, and texts the guest a confirmation or a link. It collects special requests along with the booking. VIPs, and anyone who asks for a person, go straight to staff. After each call you get the recording and a summary.

Slang answers in English and Spanish. Premium adds Slang’s newer Superhost voice, which answers in 97 languages and can switch mid-call, plus a choice of 20 premium voices and custom greetings (pricing). If your guests are mostly tourists or your neighborhood is multilingual, that’s the main reason to pay for Premium.

You can get a new local or toll-free number from Slang or keep your existing one.

What it costs

Slang publishes starting prices per location: $399 for Core and $599 for Premium, with custom pricing for Enterprise groups (pricing). The pricing page doesn’t name a billing period, but Slang’s own comparison page gives Core as “starting at $399/month” (Slang vs Sadie). Every plan still goes through a quote, and Slang doesn’t publish call limits, contract length or setup fees. Ask about all three before you sign.

Here is what $399 a month means at a typical volume. A restaurant taking 200 calls a month pays about $2 a call on Core. At 600 calls, about 67 cents. Because the price is per location rather than per minute, long calls cost nothing extra, which suits reservation calls where guests ask three questions before they book.

The per-location model adds up for groups. Three restaurants on Core start at $1,197; on Premium, $1,797. At that size, ask about Enterprise pricing, which is quoted for multi-location groups and adds custom call limits, dashboards, SSO and SLA-backed support.

Premium’s extra $200 per location buys the multilingual voice, custom voices, cross-selling to sister restaurants, real-time alerts, a smart inbox, private events capture and priority support. A single restaurant with English- and Spanish-speaking guests will usually get what it needs from Core. Our AI receptionist pricing guide covers flat versus per-minute pricing in more depth.

Setup

Slang’s own pricing page is unclear on how long setup takes: it says both “same day” and “within the first week”. Plan for the week. The work on your side is answering the questions the AI will be asked (hours, parking, corkage, kids’ menu, large-party rules) and deciding which calls should always reach a person.

Slang says it is SOC 2 Type 2 compliant. It doesn’t say whether call data trains its models.

How it compares

vs Loman. The clearest split in restaurant AI phone tools. Loman is built for takeout orders and payments into the POS, and its blog puts plans from $199 a month; Slang is built for reservations, private events and group cross-selling, from $399 per location. Loman’s terms lock you in for the initial term you choose. Slang’s terms let a new customer cancel within the first 30 days and get back the fees paid for that period; after that, each order renews for the same length unless you cancel 30 days before it ends (terms).

vs a human host. Slang won’t replace your host stand on a Friday night, but it can take the calls nobody has time for, and answer at 10am before anyone arrives.

Verdict

Slang AI is a focused tool for a specific job: answering reservation calls and questions at full-service restaurants, booking straight into the reservation system you already use. Its published starting prices are more than Loman’s pricing page shows, and Premium’s 97-language voice is a real differentiator. The gaps are the fine print. Call limits, contract length and setup fees all come only with a quote, and multi-location groups pay per restaurant. Ask for those in writing, and if takeout is your main phone business, look at Loman instead.
