Yes, I'm looking for a moderately priced restaurant in the centre.
There are quite a few moderately priced restaurants in the centre of town. Do you have a food type preference?
No, maybe you could book me at your favorite for Saturday?    There will be 8 of us, at 17:30.
Well, my personal favorite is Copper Kettle. I've booked you a table for 8 on Saturday at 17:30. Your reference number is LSQYZI7O. 
Great, thanks so much!
You're welcome. Do you need anymore assistance today?
No that was all I needed thanks for the help. Have a great day. 
Thank you, enjoy your visit, goodbye!
