I need a cheap place to dine please.
We have 22 inexpensive restaurants. What sort of cuisine would you like?
I don't care about the type of food. I need a reservation for Wednesday night.
I can book you for dojo noodle bar, how many should I book for and what is the preferred time?
Is dojo noodle bar in the centre of town? I need something in that area, please.
It is.  How many people will there be and what time would you like on Wednesday?
The reservation needs to be for 2 for 17:00 on Wednesday evening. Do they have a table then?
The booking was unsuccessful. Would like to book it at another time?
No. It needs to be t 17:00. Another restaurant in the same area and price range would work. 
Okay I booked you into the J Restaurant that also serves Asian food in the cheap price range and your reference number is 7MUMBMFD.
Thanks so much. That's all I needed.
You're welcome. Enjoy your day.
