I'm looking for a cuban restaurant.
I'm afraid I don't have any matches. Do you have any other food preferences? 
I need something expensive in Centre and it really needs to serve Cuban food.
Again, unfortunately, we don't have any Cuban restaurants listed. Is there another type of food you would like to try?
Is there a chinese restaurant in the same price range? 
I have several places. Would you like me to book it?
No, just pick your favorite and give me the address and postcode please.
There is no listings for Cuban food ,would you want something else
I was hoping for Cuban, but since there aren't any, do you have any expensive Chinese restaurants in the centre of town?
May I recommend Ugly Duckling? They're an expensive Chinese restaurant in the centre and they are quite popular.
Sure, could I get the postcode and the address please?
The Ugly Duckling is located at 12 St. Johns Street City Centre and their postcode is cb21tw. Can I assist you with anything further? 
Thank you. I also want a train for friday, from broxbourne to cambridge
There are 19 trains on Friday, do you have a specific time you want to travel?
I need to be in cambridge by 08:15.
There are 2 that arrive by 08:15. The closest to that arrival time is arriving at 07:32.
What is the travel time for that one?
That's TR5570. The travel time is 60 minutes.
And what is the price on that one?
17.90 pounds per ticket I do believe. Is there something else I can help you with today?
What time is the departure? I am sorry.
The departure is 06:32. Anything else?
I think that is all I need for today. Thank you for all your help.
You're very welcome. Enjoy your time here.
