U: I am looking for a restaurant in the centre area in the cheap price range

S: There are 15 restaurants that fit your request. Do you know what type of food you will want to eat?

U: I don't care, just as long as it's cheap and in the center of town.

S: How about Charlie Chan?  It's a Chinese restaurant that is located in the centre and is cheap.

U: Does Charlie Chan serve generous portions of food?
S: All of the reviewers complained about the portions being small and left hungry except one. Another reviewer said that all the people in their party were satisfied with food portions.
