I'm looking for a North African restaurant.
I'm sorry but it looks like I don't happen to see any restaurants that specialize in that type of cuisine? Can I help you with a different type?
How about something in the expensive price range instead?
Sure, there are 57 expensive restaurants in town. Is there an area of town you'd prefer?
I would prefer something near the centre please.
There are over 33 restaurants that meet your criteria. May I interest you in African cuisine since you originally asked for North African restaurant? 
No, I think I'd like an expensive French restaurant instead. 
Cote is an expensive French restaurant in the center of town. Would you like a table there, or possibly their address?
Yes please. Can you book it for Friday at 19:45? There will be 8 of us.
OK,  you have a table for 8 at Cote onFriday night. Your reference number is ZWI39RV9. Can I help you with anything else today?
No. That's everything. Thank you! Goodbye.
You are welcome.  Have a great day.
