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: Do they serve large portions here?
S: The portions at the Sala Thong Restaurant are  small according to a majority of guests, but some still said they were huge. I guess it depends on what you are used to.
