Task-oriented dialogue about: restaurant

I need to find a restaurant in the west part of town. It should be in the cheap price range.
I have a Vietnamese and an Italian restaurant matching your requirements. Would you be interested in either?
I'd prefer the Italian one.
I have La Margherita that is a cheaper italian restaurant. It's located at 15 Magdalene Street City Centre. Did you need any help booking a table?
Can I get the postcode for it?
Absolutely! The postcode for La Margherita is cb30af. Would you like me to make a reservation for you?
Yes, please. Thank you very much.
Great! What day and time would you like the reservation for?
I do not want to just yet, thanks.
Okay, we'll book that for you whenever you're ready. Thank you and goodbye!
