U: I want to find a European restaurant in the west.

S: There is one available, the cambridge lodge restaurant, would you like me to book you?

U: No, I'm just getting some information together.  Is it expensive?

S: Yes it is an expensive restaurant, do you want to try a different restaurant?

U: Let's go with Cambridge Lodge.  I'd like to book for 8 at 17:30 on Saturday, please.

S: Reference number is : IPXE2SID. Is there anything else?

U: actually, i want to change the reservation to sunday.

S: Reference number is : ISJVY1RC. Is there anything else?

U: I am also looking for a hotel, it can be expensive, but it needs to have free wifi.

S: There are five expensive hotels, all with wifi. Could you tell me which location you are wanting to stay in, to narrow it down?

U: The area doesn't matter, which one would you recommend?

S: Sure, I would recommend the Huntingdon Marriott Hotel which is located near the restaurant. Would you like a reservation?

U: Does it mention having a good view?
S: According to the reviews I have on hand for that location, the views there are likable.  Sound good to you?
