I'm looking for a chinese food restaurant in the centre. 
There are ten chinese restaurants in the centre area, do you have a preference for price range?
No, I don't care. Can you recommend your favorite?
I like the Lan Hong House. It's moderately prices, but good. Should I book a reservation?
Yes please check to see if there is booking for 2 people at 12:30 on sunday.
I'm sorry there are no available bookings for that time. Would you like to try something else?
Yes, how about a different restaurant in the same area and price range? 
You should try lan hong house , it is a nice place.Would you like the address ?
