am looking for a restaurant. The restaurant should be in the west and should be in the cheap price range
I have two choices in that area and price range.  Would you prefer Italian or Vietnamese?
I would prefer Vietnamese.
Thanh Binh is a cheap Vietnamese restaurant in the west. Shall I book a reservation for you?
Yes please. I'd like it to be for Tuesday at 12:00. 
How many people should I make the reservation for?
There will be 7 of us.
The booking was successful and your table will be reserved for 15 minutes. Your reference number is KH5F18TN. Anything else I may assist you with?
No that's it. Thanks for your help!
You are welcome! Have a nice day!
