Hi there. I am hoping you could help me find a british restaurant in town. 
Sure we have quite a few. Do you have a price range or area in mind?
Yes I am looking for something moderately priced.
Okay, and do you prefer a certain area of town? There are four in the centre and one in the west. 
Yes, the one in the west please.
The one in the west is Saint Johns Chop House. Its located at 21-24 Northampton Street. Can I make a reservation for you?
Yes, I would really appreciate that. Can you get me a table for 5 on Sunday at 16:45? 
I'm afraid they're fully booked for 16:45 Sunday. Perhaps a different time or day?
Is there anything an hour earlier or an hour later on that same day?
No, unfortunately. Both an hour earlier and an hour later, they're booked. 
Let's try a different restaurant. 
What is available in the centre area at 16:45 for a party of 5?
Sure, when you find something, make the booking and give me the reference number.
I have you booked at a British place in the center of town. Restaurant One Seven, reference code 5K83E181.
Thank you, that is all I need. Bye.
Have a great day!
