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: Does the Riverside Brasserie offer a fun, welcoming atmosphere?
S: Yes it does. The restaurant has really ventured in the vibe that it offers that has turned out be fun.
