U: I'm looking for a moderately priced restaurant in the center of town.

S: There are 21 different restaurants in that area matching your price range. What kind of food are you in the mood for?

U: I would like to try Jamaican food.

S: Unfortunately I can't find any Jamaican restaurants. Is there another type of food you'd like to try?

U: Okay... how about British food?

S: I found 4 restaurants, would you like to try Cotto?

U: Do you know if it has a nice outdoor place for dining?
S: If you're searching for a location with a nice outdoor area for dining, the Cotto restaurant will disappoint as they lack that particular feature.
