U: I am looking for a restaurant in the centre of town in the moderate price range.

S: Where you interested in any particular type of cuisine? I have some restaurants like that including: Indian, Chinese, and Italian. Do you have a preference?

U: Do you have south indian food? That sounds really good.

S: There are no south indian food places, shall I run another search?

U: Can you try British food instead?

S: I found 4 restaurants that meet your criteria. I recommend either the oak bistro or cotto

U: Is the service great?
S: The oak bistro has mostly bad reviews for the service. Multiple people say that the waiters are not attentive and someone says they are not friendly. One person says that they had good service. Cotto has mixed reviews about the service. People say that it is slow and one person says it was great.
