Could you help me find an Austrian restaurant please? 
I'm sorry but there are no Austrian restaurants. Is there another type that might interest you?
Darn, I was really hoping to find a cheap Austrian restaurant. Would you mind checking one more time? 
I'm so sorry but there doesn't seem to be any restaurants in the city that offer austrian food. Can I look for another cuisine style for you? 
Ok, how about a cheap Chinese restaurant?
We have four cheap Chinese restaurants. Are you interested in the south or centre area?
I am interested in the centre area.
The golden house is a cheap chinese restaurant in the center area. Would you like me to reserve a table for you?
Yes, that would be great. I'd like a table for 3 on Saturday at 18:30.
There doesn't seem to be any availability for Saturday at 18:30. Does another time or day work for you? 
Sure, try 17:30.
I was able to make your reservation for 17:30. Your reference number is VGGQ2AP9. Is there anything else I can help you with?
No that will be all.
Excellent. Have a good rest of your day.
