I'm interested in finding a restaurant that serves Tuscan food.  Do you know of any in the moderate price range?
no I am sorry I don't have anything but I'm sure I could find you something that is simply Italian.
I'm sorry. I'm only looking for a place that is moderately priced and serves Tuscan food.
I apologize, but it appears tuscan with the moderate price range does not have any result.
That okay. Italian does sound fine, actually. Could you find a moderately priced Italian restaurant instead? 
I found Prezzo in the west part of town, would that work?
Yes, that works. Please book a table for 8 people at 19:00 on Wednesday. Can you do that?
Booking was unfortunately unsuccessful. Can we try another day or time slot?
Can we book the table for 8 people at 18:00 on Wednesday please?

Thank you, that's all I need!
Thank you, goodbye.
