I want to find some information on da vinci pizzeria
I found Da Vinci Pizzeria is a cheap restaurant in the north. Would you like me to make a reservation?
Yes please.  For one person at 12:30 on Sunday.
I have you scheduled for a reservation for 1 on Sunday at 12:30, would you like a confirmation receipt?
Yes, please give me the reference number.
I am so sorry but the da vinci pizzeria is fully booked and I was unsuccessful. Do you want me to try another restaurant?
Yes how about one in the same area and price range please?
Okay I was able to book you into The Royal Spice serving Indian food and your reference number is K8N0LLBP.
Awesome! Thanks so much. That is all I need.
Thank you for using this service. Goodbye.
