U: I am looking for a Persian restaurant with expensive price range food.

S: Unfortunately I can't find any matching records. Could you like to try any other food type?

U: Oh, how disappointing. There are no expensive persian restaurants in the center of town?

S: No, I am afraid I have no listing for one. Would you like to try another area or pricerange?

U: Is there a italian restaurant in the centre of town in the expensive range?

S: Yes there are 4 italian restuarants that are expensive in the centre of town.  Stazione, Clowns Cafe, Don Pasquale Pizzaria, and Cafe Uno.  Would you like a reservation?

U: Do any of those places have really nice decor?
S: Each of the places have interior decor that is modern and beautiful. The Don Pasquale Pizzeria doesn't have the information listed.
