U: I am searching for a restaurant serving vietnamese food in the centre of town.

S: There is one Vietnamese restaurant, but it's in the West end of town. Would that work for you?

U: I prefer to stay in the centre of town. Is there a turkish restaurant?

S: 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?

U: I don't care about the price range.

S: Anatolia serves Turkish food in the centre of town. Would you like their phone number?

U: Do they serve good food portions?
S: Many customers were unhappy with the portion sizes at Anatolia, saying that they were tiny, quite small, and even stupidly small. However some would have differing viewpoints.
