I'd like to find an expensive restaurant in the centre of town. 
We certainly have plenty expensive places in the center of town! What type of cuisine are you looking for?
Honestly, I am not sure. Which ones do you show available?
We have just about anything you can think of, from Loch Fyne's seafood to Bedouin's African.
Can you make a reservation at Loch Fyne's for 4 people at 14:30 on sunday?
I was able to reserve that for you. Your reference number is 439GP4J5. Is there anything else I can assist you with? 
Thanks so much.  That is all I need.  Have a great day.
You as well, enjoy your meal!
