U: Please list all moderately priced restaurants in the centre of Cambridge.

S: There are 21 restaurants to choose from. Would you like me to narrow this search down by choosing a type of food you would like to eat?

U: I would really like some good Turkish food.

S: There are two Turkish restaurants listed. Anatolia and Efes Restaurant. Would you like to make a reservation for either of these?

U: Is the location nice?
S: The Anatolia is in a nice location but one customer says it's a little out of the way. Efes is in a strip mall and located near a lot of other things to do. Would you like more information on either place?
