The AI Phone Revolution in Restaurants

If you recently called a restaurant in New York City, Miami, Atlanta, or San Francisco, chances are you spoke to an AI voice host like Jasmine, part of a growing clan of polite, calculated competitors transforming restaurant communications. (Hostie AI) These AI systems offer around-the-clock phone hosting that can answer generic questions about dress codes, cuisine, seating arrangements, and food allergy policies.

The business case is compelling: "The phones would ring constantly throughout service," explains one restaurant owner. "We would receive calls for basic questions that can be found on our website." (Hostie AI) With human hosts earning around $17 per hour - barely enough to cover gas costs - restaurants are turning to AI solutions that never call in sick and work 24/7. (Hostie AI)
