Can you find me an expensive restaurant in the centre?
There are 33 restaurants that meet that criteria. Are you looking for a certain type of food?
I want Chinese food and the restaurant needs to be located in the centre area.
There are four expensive chinese restaurants located in the centre. I recommend hk fusion. Would you like me to make you a reservation?
Excellent, lets try HK Fusion for 5 people at 19:15 on Friday. 
I am sorry this booking was unsuccessful. Maybe another time perhaps?
Please, try booking anytime between 20:15 to 9:15 on Friday.
None of the times are available do you have another restaurant preference?
Any other place in the centre, same expensive price range. 
I was able to book bedouin, reference number is 4ATMIYSC

Okay great. I am glad I could be of help.
