Task-oriented dialogue about: restaurant

I'd like to find an expensive place to dine that specifically serves italian food.
Okay. Would you like to go to the centre or south part of town?
I would like the south part of town please.
Frankie and Bennys meets you criteria, would you like me to make a reservation for you?
Yes, please. There are 4 of us for this Friday at 16:00.
Booking was unsuccessful. Perhaps another day or time?
how about 15:00 instead?
Okay, that worked, and I've successfully booked your table. I can give you the reference number, if you'd like.
Yes, I will need the reference number.
Your Reference number is : VRU8VSG0 . Do you need any further assistance?
No that was everything I needed. Thank you for your help!
You're very welcome. Have a good meal!
