U: I would like a restaurant that serves world food

S: Im sorry, there are no restaurants that serve world food. Can I help you with something else?

U: How about portuguese food?

S: Nandos serves Portuguese and is located in the south part of town and is in the cheap price range.

U: Does Nandos serve portion sizes that are large?
S: I'm not sure.  One person said that the portions were huge another said that they were small.  Do you want to make a reservation?
