U: I need a restaurant in the east part of town that serves world food.

S: I found no matching records for your requests. Do you want to try something else ?

U: How about chinese food?

S: Yu Garden is a great Chinese restaraunt on the east side of town. Should I get you their phone number?

U: Does this restaurant have a good view?
S: No, Yu garden is not known for its great views. Would you like me to find something with a nicer view?
