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 have a large selection of beer?
S: I'm not sure. Some customers said that the drink selection was a bit small though. Would you like to look at another location?
