The Problem

Staff can't answer phones during service rushes

01

Phone calls go unanswered during peak hours — missed reservations and takeout inquiries

02

Customers call for basic info: hours, menu items, dietary options, directions

03

WhatsApp messages pile up during busy periods with no one available to respond

04

No structured way to capture what customers ask about most frequently

The Solution

AI phone + WhatsApp agent for hours, menus, and reservations

An AI voice agent handles calls during busy periods — answering questions about hours, menu items, dietary accommodations, and directions. WhatsApp bot handles text inquiries 24/7. Special requests and large party reservations escalate to a manager automatically.
