Hi.  Could you help me find an expensive restaurant that serves Catalan food?
Unfortunately, I don't show anything available meeting those requirements. Can I try a different price range or type of cuisine for you?
How about something in the centre of town
I was able to find bedouin in the centre of town in the expensive price range.
The Bedouin serves Catalan cuisine?
The Bedouin serves African food.
Oh okay. I must have been mistaken. Let's try something that has italian, is expensive and in the centre of town. 
How does don pasquale pizzeria sound to you?
Sounds good, lets book it for 4 people at 14:00 on Wednesday, and I'll need a reference number please.
Booking was successful. The table will be reserved for 15 minutes. Reference number is : CORC123E.
Thank you so much!
