Hi, I am looking for a north Indian restaurant in the town centre?
I've found 9 restaurants that match what you're looking for. Would you like me to go through them?
One in the moderate price range would be good. Can you find one for me?
I am sorry there are non in the moderate price range,I have a few in the cheap price range,would that be okay?
No, in that case I think I would prefer to try a place that serves international food.
I have 2 restaurants that meet your needs: The Varsity Restaurant on Saint Andrews St. and Bloomsbury Restaurant on Downing Street.
Okay, how about The Varsity .. I'd like a table for four on Thursday at 12:30.
Booking was unsuccessful, want to try another restaurant??
Yes. I'd like the same area and price range.  
Okay I was able to get you into the Bloomsbury and your reference number is 6BOHROUH.
Thank you, that will be just fine. 
You're very welcome! Don't hesitate to call if you would like help finding other attractions.
