I need a train to Ely, please.
What day will you be traveling?
I will be leaving Sunday after 19:30.
Can I ask where you are leaving from?
I will be leaving from Cambridge on Sunday after 19:30.
I have train TR3544 leaving at 19:50 and arriving by 20:07. Would this work for you? 
No need to book it.
OK. Can I help you with anything else today, then?
Yes.  I am looking for places to go on the west side of town.
Yes I have many colleges there. Can I suggest something for you?
Can you suggest some good architecture attractions?
Unfortunately, I'm not showing any architecture attractions in the west area.  Would you like me to look in another area?
What type of colleges are available?
There are five colleges on the west side. Churchill college, Clare hall, and Magdalene college all have free admission. Do any of those interest you?
Clare Hall sounds like it would be nice. Can I get their phone number please? 
The phone number is 01223332360. Is there anything else I can help you with?
I think that is all I need. Thank you for your help. Goodbye. 
It was a pleasure to assist you. Thank you for using our service. Goodbye.
