U: I'm looking for a restaurant in the centre area in the moderate price range.

S: There are 21 places to dine at with moderate pricing, do you have a preference for cuisine type?

U: Yes I would like european food.

S: There are 2 to choose from.  They are both good, but I like the Galleria personally.  There are also a few that serve modern european food.

U: No, I'll try the Galleria. Can you book a table there for 2 at 15:30 on Tuesday, and please provide me with the reference number?

S: Booking was successful. The table will be reserved for 15 minutes.
Reference number is : T7QJ1WB2. Anything else you need?

U: Yes. I am also looking for a place to stay that's in the same area as the restaurant with free parking.

S: I have 2 guesthouse and 2 hotels in the centre. Do you have a preference or a price range in mind today?

U: A 2 star would be good. I don't care about price range.

S: I'm sorry, we don't have any 2 star hotels or guest houses in that area.  Would you like to try something else?

U: How about guesthouses with 0 stars?

S: I have the El Shaddai guesthouse. It is cheap and in the centre of town. It has free parking and internet. Would you like me to book you a room?

U: Can you confirm that El Shaddai Guesthouse is very clean?
S: The El Shaddai has several reviews stating that the rooms were clean, and a few more stating that they were not clean. Would you like to book a room?
