Are there any Australian food places in the south part of town?
I was not able to find any Australian restaurants in the south part of town
Are you sure? I am really looking for an expensive Australian place to dine in the south. 
Yes, there are no expensive Australian restaurants in the south part of town. Would you like to look in a different area?
No, lets keep the same area but see if there might be an Indian restaurant instead. 
How about Taj Tandoori? It is an expensive Indian restaurant in the south side. 
Okay. I want to book a table for 5 people at 16:30 on sunday.
I was not able to book you a table for this time. Would you like to try a different day or time?
Can you see if a table is available at 15:30?
I was able to book a table of 5 for 15:30 at Taj Tandoori on Sunday. Your reference number is HJZCPH80, your table will be reserved for 15 minutes.
Great thank you for your help today.
It was my pleasure. Was there anything else I could assist you with? 
No, that's it for today. Goodbye.
Thank you for calling in, enjoy!
