I am looking for information about the museum of archaeology and anthropology. 
That museum is located over at University of Cambridge, downing street. It's free to visit.
Could you please provide me with the postcode.  Thank you!
The post code is cb23dz.
I also need a train, to cambridge, I want to arrive by 17:45.
There's a train that leaves at 13:17, want that one?
As long as it arrives in Cambridge by 17:45 and departs from Broxbourne that will work.
What day do you need the train? 
I will travel Tuesday. 
Is there a time you need to leave or arrive by?
I need to arrive at 17:45.
I have one arriving at 7:32 will this work for you?
Thats perfect. What is the price and travel time on this train?
It is 17.90 pounds and takes 60 minutes. Would you like me to book this for you?
No thanks, just gathering information, that is all I need.  
Can I help you with anything else? 
That is all I needed today. 
Glad I could help come backk if you need anything else
