Can you help me find a train leaving Cambridge at 5:30pm on Friday?
Where will you be traveling to?
Let me change the day to Sunday leaving Ely for Cambridge after 10:15,
I would recommend TR6517 which departs Ely at 11:35 and arrives in Cambridge at 11:52. 
Ok.  That one sounds good.
How many tickets will you be needing for your trip?
I'm not sure but I would like some information about museums in the south.
The Byard Art museum matches that criteria. What information do you need? 
May I please have the entrance fee, phone number, and post code?
Free to enter. 01223464646, post code cb21sj. Anything else?
No. That's all. Thanks so much!
You are very welcome. If you don't need anything else go ahead and close the chat.
