U: Hi there. I'd like to find a place to dine in the city centre, preferable with Sri Lankan food. Do you have any recommendations?

S: Sorry, I don't have any restaurants with sri lankan food in the centre. Would you like to try another type of food?

U: Could you try again? Moderately priced, perhaps?

S: Sorry, there was nothing found. Do you want to try a different kind of food?

U: How about modern european food?

S: There are two options for modern european food in centre in the moderate price range.  May I suggest Riverside Brasserie?

U: Is it in a safe area with lots of entertainment options?
S: If one can overlook the fact that the Riverside Brasserie is situated within a nondescript strip mall, the location could be considered quiet nice.
