U: I am looking for a nightclub to visit while in town.

S: There are six nightclubs in town; 5 in the centre and 1 in the south. Do you have a location or other preference?

U: Yes i would like to be in the center.

S: I have 5 nightclubs in the centre area, my personal recommendation is the soul tree nightclub, would you like more information on the soul tree?

U: Sure, what's the soul tree's address and postcode?   I'm also looking for an expensive danish restaurant.

S: The address is 1-6 corn exchange street and the postcode is cb23qf. There are no danish restaurants in cambridge. Do you have another food type you would want to try?

U: Do you have any restaurants in the same area as the attraction?

S: There are 69 restaurants in that area. Do you have a preference for the pricerange?

U: Do you have some place that serves Danish food and it should be expensive?

S: I'm sorry there are no Danish restaurants in the centre. We do have others like Chinese, Italian, etc. Do you have another preference?

U: Indian, please.

S: There are 6 results. May I make a recommendation?

U: Yes, please. Although I would like it to be in the centre of town.

S: The curry garden is  a great indian restaurant in the centre.  Can I book a table for you?

U: Do they serve good value Samosas?
S: Some people says yes, some people say no. The food there is high quality, and you get decent portion sizes, so it seems like it is worth the price.
