U: Hi, I am looking for a north Indian restaurant in the town centre?

S: I've found 9 restaurants that match what you're looking for. Would you like me to go through them?

U: One in the moderate price range would be good. Can you find one for me?

S: I am sorry there are non in the moderate price range,I have a few in the cheap price range,would that be okay?

U: No, in that case I think I would prefer to try a place that serves international food.

S: I have 2 restaurants that meet your needs: The Varsity Restaurant on Saint Andrews St. and Bloomsbury Restaurant on Downing Street.

U: which has better service?
S: The Varsity Restaurant has better reviews of the service, although it can be a bit mixed at times there.
