U: I am looking for a Cuban food place, in the east.

S: I am sorry but there aren't any restaurants matching your criteria. Can I help you with something else?

U: Can you check again? The only thing I'm interested in is a moderately priced Cuban restaurant in the east.

S: I apologize I am still not showing any restaurants that meet your criteria.  Is there another type of cuisine you would prefer?

U: Do you have a moderately priced Indian restaurant in the east?

S: Yes I have 2. Curry Prince and Rajmahal.

U: Which of these are known for having good service?
S: The staff at the Curry Prince are better than those at the Rajmahal according to customer reviews.  Would you like me to make a reservation for you?
