I'm visiting cambridge, I want to spoil myself, I am looking for a four star place to stay which is expensive.
Sure, I can help you with that.  There are two places.  One is in the west and one in the centre.  Do you have a preference?
It doesn't really matter what area. But, I really prefer a hotel over a guesthouse. Do you have any? 
I have two options, the Huntingdon Marriott Hotel or the University Arms Hotel. Do you prefer one over the other?
We were wanting to have free wifi. Do either of them provide that?
Both of these two offer free wifi, The Marriott is in the Hinchinbrook Business Park, while the University Arms is on Regent Street downtown.
I would like to book the University Arms for five nights. Could you do that for me?
I can! When would you like the booking to start? And how many in your party?
2 people and 5 nights starting on teusday
Booking was successful.
Reference number is : F063DE8D
I am looking for a place to dine
Okay, do you have a food, price range, or area preference?
It should be in the north and it should be expensive.
We have asian oriental, 2 chinese, a european and french to choose from, any preferences?
A French restaurant is fine.  Can you make a recommendation?
Yes, I recommend Restaurant Two Two at 22 Chesterton Road, Chesterton.  Can I reserve a table for you?
Yes, please. The reservation will need to be for Tuesday, 2 people, and we'd like to dine at 15:15. 
Your booking was successful. The reference number is 928SYN1A. Your table will be reserved for 15 minutes. 
I'd like to book a taxi from the hotel to the restaurant to get there by 15:15.
Thank you.  Goodbye.
