U: I'm looking for a place to dine that serves welsh food.

S: There are none in the area that serves Welsh food, would you like to look for another type of cuisine?

U: Is there one that serves Italian food?

S: There are 15 italian restaurants. Do you have preference in food price or area?

U: I'd like a moderate price range, please.

S: I have 5 moderately priced Italian restaurants.  Do you have a preference on area, they are spread around the east, west, south, and centre.

U: I don't have an area preference, but I would like to book a table for 6 people at 16:45 on wednesday.

S: You are booked into Prezzo which is moderately priced on the west side. Your reference number is G2FIPHUL. Is there anything else?

U: Does Prezzo have a nice view that patrons can enjoy?
S: The Prezzo has a great view according to some guests, but others find it to be mediocre. It may depend on where you are seated.
