I'm looking for an expensive place to dine in the centre.
I have 33 restaurants that meet that criteria. Are you looking for a certain type of food?
I would like north american food.
gourmet burger kitchen is an expensive restaurant that serves North American Food. Would that be acceptable?
Sure please book for 7 people on wednesday at 19:15 please.
Unfortunately, we were not able to book that restaurant. Would you like me to try and find another restaurant?
Are there any other options in the expensive price range in the centre? 
I was able to find 3 that serve british food and 1 that serves african and 1 that serves asian. Do you have a preference?
Can you book me in for the Asian restaurant then?
Okay. I was able to book you a table at the kymmoy. Your reference number is TQVKVLNH. Is there anything else you need? 
Nope, I think that will do it, thank you
It's my pleasure. Have a great day! Goodbye!
