U: Yes, I am looking for a place to dine. I would prefer the city centre and am looking for halal food.

S: I am sorry I can find no place that serves that in the centre area. Would you like to try another area or food type?

U: Ok. Is there an Indian restaurant in the centre area.

S: There are five Indian restaurants in that area, what is your price-range?

U: I don't have a price range. Can you just recommend one of the five restaurants and tell me the postcode and the price range

S: I apologize. There were 9 differrent indian restaurants in the centre of town. My recommendation would be Panahar. They are expensive. Their postcode is cb12lf. Anything else I can help with?

U: I'm really hungry, can you tell me if they're known for large portions?
S: The reviews regarding portion sizes run the gamut from rather small to very generous and huge. It may depend on your point of view. I can look into it a little further if you'd like.
