Can you find me a restaurant that is located in the centre and is in the moderate price range?
Of course! There are 21 such restaurants available. Do you have a preference for the type of food?
Yes, Australian, please.
I actually do not have knowledge of any moderate Australian restaurants in the centre. There are some British restaurants I could inform you about.
Actually, could you look up some turkish restaurants instead?
There are 2 Turkish restaurants, the Anatolia and Efes Restaurant. Would you like me to make a reservation at one of them for you?
Yes,I need to book a table for 6 people at 17:00 on Sunday, please.
I have made a reservation at Efes Restaurant for 6 people on Sunday at 17:00.  The reference number is 8NR6PAIM.  Is there anything else I can help you with?
No, that is all, thank you good by. 
Thank you, let me know if you need anything else, bye.
