Yes, I'd like some information on finding a particular restaurant. The restaurant should serve a variety of Jamaican food and ideally I'd like it to be located in the south please.
I'm sorry but I have no Jamaican restaurants located in the south. Could we try another part of the city or different food type?
No I am looking for that specifically. 
Then we have a problem, because such a restaurant  does not exist. I'm sorry. Is there anything else I can help you with?
How about one that serves italian food?
I have listings for 2 italian places,one moderate and one expensive, which one you like information on?
I'd like to book at the expensive place. There will be 8 of us, and we'd like to eat at 15:00 on Monday.
I apologize the booking was unsuccessful.   Would you like to look at another restaurant
Can you find me another restaurant int he same area and price range please?
Would you like to try chiquito restaurant bar? 
Yes please try booking that for me.
Wonderful. I was successful in booking The Chiquito restaurant for you and your reference number is OCGZRNU0.
Thank you so much for all of your help. That will be all.
You are welcome. Thank you for contacting Cambridge TownInfo centre. Have a great day!
