Can you tell me where I can find an expensive chinese restaurant?
There are 9 expensive Chinese restaurants. Do you have a specific area you would like?
I would prefer the city centre please.
I have 4. How about hk fusion?
I would like to book a table for 6 people at 13:30 on Sunday.
The booking for hk fusion was unsuccessful. Would you like a different restaurant?
Will try another one in the same area and price range? If you can book it, will you give me the reference number?
You are booked into the ugly duckling which is in the expensive price range in the centre of town. Your reference number is 3RFXW8G6. Is there anything else?
No, that is all. Thank you, good bye. 
Okay enjoy your lunch and thank you for calling.
