U: I would like to find in Cambridge, a restaurant, located in the Centre area.   I love spanish food.

S: I have La Tasca downtown here at 14 - 16 Bridge street.

U: The restaurant should be in the expensive price range

S: I do not have any in the centre, another criteria perhaps?

U: How about african food?

S: I was able to find bedouin, would you like to try that?

U: That would be great, could you just give me their number?

S: The number is 01223367660. Is there anything else I can help you with?

U: I also want to find an expensive place to stay with a star rating of 3 please.

S: With that criteria, I have two different options for you. Both are hotels and offer free parking and wifi. One is in the centre of town and one is south.

U: I want one that is in the same area as Bedouin, please.

S: The gonville hotel is in the centre which is the same area as Bedouin. Would you like me to book it for you?

U: Can you tell me if The Gonville hotel has relaxing beds so I can get a good night rest?
S: The Gonville hotel has really comfortable beds. Are you interested in getting a booking or do you have any other questions?
