I want to know where I can go in the town centre of Cambridge.
There are many places to go in the centre. Are you looking for an attraction or restaurant?
An attraction of any type would be fine as long as it's in the centre, please.
I could recommend old schools. It is architecture and free to see. Would you like more information?
Yes tell me one of those recommendations. 
Old Schools is an architectural attraction on Trinity Lane that has no entrance fee. Their phone number is 01223332320. Can I help you with anything else?
Can you provide me the full address including postal code?  Thanks.  
The address listed for Old Schools is simply Trinity Lane. And their postcode is cb21tt. Is there anything more I can do for you today? 
Yes, I would also like to find an expensive restaurant in the same area.
What kind of food would you like and what price range
I would prefer British food and an expensive price range if possible.
I have three restaurants in the town centre that meet your needs.  Might I suggest the Cambridge Chop house or Fitzbillies restaurant?
Can you please recommend one and give me their postcode and phone number? 
The Cambridge Chop House is a favorite of mine. It's located at 1 Kings Parade. Would you like me to book it for you?
No thanks, but I am interested in getting a tax from Old Schools to the Cambridge Chop House. Can you help?
What time will you be needing the taxi service for?
I would like to leave Old Schools by 19:00.
Okay your all set! A red lexus will be picking you up the contact number is 07885505407, is there anything else I can help you with today?
Thank you that will be all I need.
I'm happy to have been of service. Goodbye!
