I am looking for a caribbean restaurant in the centre of the city.
Regretfully, there are no caribbean restaurants in the centre. Would you like to try something else?
Are there any caribbean restaurants in any other part of town?
I am sorry there are none in any area of town,is there another type of food you would be interested in?
Sure, a turkish restaurant in the moderate price range would be great.
I have 2 turkish restaurants in the centre. The anatolia or efes restaurant are both moderate. Would you like me to book one for you?
Yes, book me The Anatolia for 8 people at 12:00 on Friday.
I'm sorry, there are no available seats at that time. Would you like to try Efes restaurant?
Yes please try booking that.
Yes I was able to get you into that restaurant and your reference number is  46AL3F0C.
Great! Thank you so much for your help. That will be all.
Okay. Great. Enjoy your lunch.
