I am searching for a restaurant serving vietnamese food in the centre of town. 
There is one Vietnamese restaurant, but it's in the West end of town. Would that work for you?
I prefer to stay in the centre of town. Is there a turkish restaurant? 
Yes there are three restaurants serving Turkish food in the center of town in the moderate and expensive price range. Which price range would you prefer?
I don't care about the price range.
