Hi! I'm looking for a cheap restaurant in the north, any type!
There is Royal Spice which serves Indian food and Da Vinci Pizzeria which serves Italian food. Would you like me to book you a table at either of these restaurants?
Royal Spice sounds good. Can you reserve a table for 8 at 15:45 on Saturday? 
Unfortunately, I was not able to book for that specific time and day. Can I try a different day or time for you? 
How about at 14:45? 
I've booked it for that day on Saturday. Reference number 9PVIPW1Y. Anything else?
No, you have been very helpful. Thanks, goodbye.
Thank you, and have a great day!
