U: Hello, I am looking for an expensive restaurant that serves cantonese food.

S: Sorry, there are no expensive restaurants serving cantonese food. Would you like to look for something else?

U: Yes.  An expensive thai restaurant would be good.

S: Bangkok city serves Thai food and is in the expensive price range.

U: Are the food portions good?
S: The majority of the customers at Bangkok City would like the portions to be much larger. There are some comments that the portion sizes are large. Would you like me to look into it a bit further?
