Yes, please help me find a restaurant in the center of town.
There are 69 restaurants in the centre of town.  You can narrow it down further by price range or cuisine type. 
It should be in the moderate price range.
I have 4 that serve british food and 1 that serves asian. 
I would like to book the asian one for tuesday.
What time and for how many people would you like to book?
19:00, for 6 people.
The booking was unsuccessful, would you like to try a different location?
As long as its in the same area and price range that will be fine I also need the reference number too
I was able to get you a booking at restaurant one seven.  It is british. Will that one be good?
Yes can, I please get the reference number?
Okay your reference number is 9RXQYEIO.
Thank you for all your help.
You are welcome. Have a great day!
