About Ultimate AI Receptionist for Restaurants

Hi there,

I watched the "Ultimate AI Receptionist for Restaurants" tutorial, it was amazing but it was made on Make.com, so I have to convert it into N8N Version with Retell, I added few things as well like storing all the data in Google Sheet. The problem that I was facing is as follows:

For Reservations/Checking availability instead of doing it manually I used AI agent to do every thing.
But for some reason the prompts were not working for Pickup and Delivery (Even thou I tried different methods, like providing variables, giving examples and of course asking ChatGPT :)).
I then realized that Pickup and Delivery acutally doesn't require AI as they are just adding row into the sheet, creating an Event and sending the confirmation email.
So I created separate workflows for each of them and calling them when needed.
I tried using "Headers" to separate the function call from Retell and use "Switch" Node at N8N but for some reason it was not "coming to the party". Ideally it should work as that is the purpose of Switch node.

Now my question:
