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: Sure.  Do you know off hand if they have outdoor seating there?
S: Yes, they offer outdoor seating with a great view. Can I answer any other questions or book a table for you?
