I'd like to find an expensive restaurant in the north part of town.
There are many restaurants in the North that match your description, what type of cuisine are you interested in?
The restaurant should serve asian oriental food.
I have one restaurant called saigon city on 169 high street chesterton chesterton. Would you like me to book for you?
Yes, I would like to be booked for a table for 8 on 19:45 on a Saturday, and could I also get the reference number?
Your reservation has been made and the reference number is 3P2ALRY0. 
Thank you for your help.
You are welcome.
