I'm looking for a chinese restaurant.
There are many Chinese restaurants do you have a price range or an area you'd like to eat at?
I would like the expensive price range. 
We have 9 expensive Chinese restaurants across town. Do you prefer a specific area of town?
I don't have a preference, just give me the phone number of the one you would recommend.  
I like the good luck chinese food takeaway.  The phone is 01223244149.  What else can I do for you?
I need to catch a train to London kings cross. I need to get there by 09:15. Can you find me one?
I will need your departure location and day of travel to complete the request.
OKay, I will be leaving from Ely.
What day would you like to travel?
Oh, I'm sorry, I meant I'm leaving from CAMBRIDGE to london kings cross on Sunday. 
I have updated the search, what day will you need that?
Sunday, please. I just said that.
TR7423 leaves at 5:00 and arrives at 5:51. Would that work?
That will be perfect! Could you book me 1 seat please? 
Okay, you are booked on that train.  Your reference number is NNZ8E0N7. Can I do anything else for you today?
Thats all for today! Thanks so much! 
Your welcome, have a great day!
