The phone agent restaurants actually keep
Overview
Slang.ai is the clearest example in this category of why vertical beats horizontal. Restaurant phone calls are a narrow, high-volume, highly repetitive problem — hours, reservations, parking, dietary questions, party sizes — and Slang has tuned specifically for it, including handling the noisy environment and rapid speech patterns of a real restaurant. It integrates directly with OpenTable, Resy and Toast rather than through generic middleware, so reservations land correctly. Restaurants report it deflecting the large majority of calls without escalation. It is useless outside hospitality, and the multi-location pricing climbs quickly, but within its lane nothing generic comes close.
Our verdict
The strongest vertical execution in this category and proof that industry-specific tuning beats general capability. If you run restaurants, this is the pick and it is not close. If you do not, it is irrelevant — there is no horizontal use case here.
Best for

Pricing starts around $199 per month per location with a bundled call allowance. Multi-location groups are quoted, and total cost scales with the number of venues.
