U: I'm looking for a cheap restaurant that serves world food?

S: Unfortunately there are now restaurants that meet those specifications. Would you like me to look for a different kind of food?

U: The restaurant should be in the north.

S: The only restaurants in the north serve Asian Oriental, Chinese, European, French, Indian or Italian food. Would you like to change to one of those?

U: Tell me about the Indian restaurants in the north then please?

S: There are two Indian restaurants, the nirala and royal spice. The royal spice is in the cheap range and the nirala is in the moderate price range.

U: Can you assure me that the place has a nice view?
S: The view from the Royal Spice restaurant is something to behold as one can see the whole city, while at the Nirala there's beautiful scenery of the heart of the city.
