U: Hi, I'd like to find an expensive cantonese restaurant.

S: There are no restaurants in the area that match your preferences.  Is there anything else you'd be interested in?

U: How about North American food?

S: Gourmet Burger Kitchen serves North American food, is in the expensive price range, and is in the centre part of town. Would you like the phone number?

U: Is this location in a safe neighborhood, close to other attractions?
S: The Gourmet Burger Kitchen is in a neighborhood, but I'm not sure exactly what it is like. Do you want a reservation?
