I'm looking for a high end restaurant in the centre, can you help me out?
I have 33 restaurants that meet that criteria. Is there a certain type of food you are looking for?
I want one that serves light bites. 
I am sorry but not results came up with your criteria, would you like to try something else?
What about one that has Italian food?
I have 4 restaurants that come up, based on that criteria. Would you like more information about them?
That's okay, I'll just pick the first one. Can you make a reservation for 2 at 15:30 this Monday?
I apologize booking was unsuccessful.  Would you like me to try another restaurant? 
Yes, please try another one of the 4 restaurants you found.
You are booked into the clowns cafe at 54 King Street City Centre. Your reference number is I0EPBDJ4. May I help you with anything else?
Thanks so much for your help
You're welcome. Goodbye!
