I want afghan food in the centre of town.
What price range are you looking for?
Any price range will be fine.
What area are you looking for?
Centre part of town. 
There are no restaurants that serve Afghan food in the center of town.
How about a place serving Turkish food?
There are three restaurants, the locations are Bridge Street city centre, King Street City centre, and the more expensive is on Mill Road city centre. Which do you prefer?
I don't care
Anatolia meets your criteria. Would you like their contact information?
Yes, what is their price range and address?
Anatolia is in the moderate price range and is located at 30 Bridge Street City Centre.
Thank you. Good bye.
