U: I'm looking for a Chinese restaurant on the south side of town.

S: There are 2 expensive and 1 cheap restaurant matching your criteria. Which price range do you prefer?

U: Book me a table for 7 on Thursday at 17:30 and send me a reference number. Thank you.

S: Would you like to book cheap or expensive?

U: I don't care what price range it is in. I will need a reference number please for the reservation.

S: Let's decide on the lucky star. Unfortunately, that appears to already be booked. Do you want to try one of the others?

U: Yes please. Let's try the other one you mentioned.

S: Ok, I've booked a table for 7 at 17:30 on thursday at the good luck chinese food takeaway. Your reference number is LA1YYDOO.

U: Can you help me find a place to stay

S: No problem, there's the aylesbray lodge guest house which is also in the south area. It's moderately priced, four stars, with parking and internet. Would you like me to book this for you?

U: Do they have spacious rooms?
S: The rooms at the Aylesbray lodge are nice and big, but I could only find one review on it. Do want to book a room?
