Can you find me an expensive restaurant in the centre?
There are 33 restaurants in the Centre.  What kind of food are you looking for? Or is there a certain price range that you need?
I am looking for an expensive restaurant that serves Indian food.
Yes I have the Curry Garden at 106 Regent Street City Centre. Would you like their telephone number?
I would actually like to book it for 6 people at 13:45 on Sunday.
That booking was unsuccessful. Would you like to try a different day or time?
Can you try to book for 6 at 12:45 instead? And if it is availabe, can I get a reference number for my booking?
The booking was successful. The reference number is W3EIFXN1. Is there anything else I can help you with?
Could you tell me about a place to go in town, maybe a college?
There are 5 colleges in my search. Is there a specific area you want it to be in?
There is not. Can you give me the address for one of the colleges? Also I would like to know which area it is in.
christ's college is in the centre of town at saint andrew's street
That sounds good.  What's the address?
Hold on while I look up the address for Christ's College.
Thank you. Please tell me the area and address of Christ's College. 
It is the centre and the address is saint andrew's street.
Great thank you for all your help, that's all I needed today.
You're welcome. Have a nice evening.
