A chat agent that shows the menu with live stock, answers FAQs and records orders in Google Sheets.

  • n8n
  • AI Agent
  • Google Gemini
  • Google Sheets
  • Chat memory

The problem

On a busy day, restaurant staff answer the same questions again and again: what is on the menu, what is in stock, how to order. Slow replies and mistyped orders cost sales.

The solution

A chat agent greets the customer, shows the menu with live stock from a Google Sheet, answers FAQs, asks for the customer's name and records the order in an orders sheet. It remembers the conversation, so customers can order in plain language.

How it works

  1. A customer writes in the chatThe message starts the workflow.
  2. The AI agent reads the messageA Google Gemini model works out what the customer wants. Chat memory keeps the conversation together.
  3. It checks the business dataThe agent reads the menu with stock levels and the FAQ from Google Sheets.
  4. It takes the orderIt asks for the customer's name and adds the order to the orders sheet.
  5. It replies in the chatThe customer gets the menu, a stock answer or an order update in plain language.

See it working

Demo recording, about 3 minutes: the customer asks for the menu and places an order, and the agent checks stock in the sheet.
The n8n workflow: a chat trigger feeds an AI agent connected to Google Gemini, simple memory and three Google Sheets tools for inventory, orders and FAQ.
The n8n workflow. The WhatsApp nodes on the right are the next step, still being connected.

What the demo shows

  • A greeting that offers three options: place an order, FAQ and information, or check an order and stock.
  • The menu listed with how many of each item are left, read from the sheet.
  • An order for six Signature Chicken Burgers accepted after the agent confirms enough are in stock.
  • The agent asking for the customer's name to complete the order, then adding it to the orders sheet.

A good fit for

  • Restaurants and cafes
  • Takeaway and delivery businesses
  • Any shop with a menu or catalogue and repeat questions

In progress: connecting this agent to WhatsApp. See what I am building now.
