U: I'm looking for an expensive restaurant that serves Thai food, please.

S: There is one in the west and one in the centre of town. Do you have a preference in area?

U: I don't have a preference in the area. I suppose you could book me a table for two people at 12:30 on Saturday. Also, could i get the reference number?

S: I booked you a table at the sala thong in the west area for 12:30 Saturday.

U: Thanks, please provide the reference number.

S: The reference number is XLRSFB9Q. Is there anything else that I can do for you?

U: Thank you for booking that. Could you please book me a taxi to leave from the centre of town at my hotel to the Sala Thong for Saturday at 11:30?

S: In order to book the taxi, I will need the location of your hotel.

U: I need to find a restaurant in the wast part of town.

S: The Sala Thong restaurant is in the west part of town.

U: Can you confirm whether the Sala Thong Restaurant has appealing views?
S: I found one review and which the customer said the view was beautiful. Would you like more information?
