Can you help me find a place to eat located in the centre that serves british food?
There are 7 places in the centre area that serve British cuisine, do you have a preference on price range?
Yes, actually. Is there one that is expensive?
Yes, I've found three all in the city centre. Is there one of these that you would prefer? 
What are their names? I need to choose one I can book a table at.
they are fitbillies restaurant, the cambridge chop house and the midsummer house restaurant
The cambridge chop house sounds good. Could you book it for 5 people at 19:45 on monday?
Unfortunately, there is no availability for your party at that time. Would you like to book a different time slot or day?
Yes, can you try the same for 18:45 instead?
You're booked and the reference number is BQT142V9. The table will be reserved for 15 minutes. Is there anything else you need?
Thank you and Goodbye 
If there is anything else I can help with you please call back.  Thank you and have a great day!  Goodbye!
