I am looking for an expensive restaurant in the centre
There are 33 to choose from. Any type of cuisine you'd prefer?
I don't care what cuisine. I would like a table for 1 at 12:30 on Thursday. I will need a reference number also.
Sure. I booked you into the Cambridge Chop House on Thursday at 12:30. Your reference number is 8NI5A15M.
Okay, wonderful. Thank you for your help. 
Was there anything else I could assist you with today? 
No, you were extremely helpful. Thank you. Goodbye.
Thank you for booking with us today. Enjoy your reservation!
