Run a restaurant voice assistant for reservations and orders

Tools

n8n

Overview

This repository contains n8n workflows that I have designed and built for practical AI automation and business use cases.

Workflow

The author built fifteen reusable n8n automation workflows for business use cases, including an AI restaurant voice assistant. This specific workflow connects ElevenLabs Conversational AI to n8n webhooks to handle table availability, reservations, orders, and human callbacks. It uses Google Sheets for operational records and Gmail for staff notifications, with JavaScript handling logic. The source describes the design and structure but does not confirm live execution or human involvement during operation.

Reported result

The source does not report any measured outcomes, success rates, or operational metrics for these workflows. It presents them as reusable examples and starting points rather than proven production systems. No evidence exists of actual business impact or failure rates. A proposed acceptance check would be to import the workflow, connect test credentials, and verify that a simulated call correctly updates a test Google Sheet and sends a test email.

Human role

The original post does not say how a person stayed involved.

Limitations

These workflows are provided as examples requiring users to supply their own credentials and secure public endpoints. Users must review logic, permissions, privacy requirements, API usage, and service costs before production use. The source does not specify how humans stay involved in the loop during live operations. Integration uncertainty exists regarding specific API limits and costs for ElevenLabs, Google Sheets, and Gmail.

Try it

I want to set up the AI Restaurant Voice Assistant workflow from the n8n-workflows repository. First, clone the repository and locate the 'AI Restaurant Voice Assistant' folder. Read the README to understand the architecture. Import the workflow.json into my n8n instance. I will provide my own ElevenLabs, Google Sheets, and Gmail credentials. Replace all placeholder values in the workflow with my actual IDs and keys. Before activating, I need to test with non-production data. Create a test Google Sheet with headers for reservations and orders. Configure a test Gmail account for notifications. Simulate a webhook call from ElevenLabs with a sample reservation request. Verify that the n8n workflow correctly parses the request, updates the test Google Sheet, and sends a test email to my staff. Show me the execution logs and the resulting email draft. Do not activate the workflow for live traffic until I confirm the test results are correct. If any step fails, stop and report the error message. Ask me for clarification if any required credential or configuration detail is missing.
