Hi there. Can you help me find a museum in the west part of town? 
Yes there are many. Do you have a preference for type?
As long as it's a museum in the west, I'm happy.  Can you pick one and give me the postcode?
cafe jello gallery is a museum in the west. Its postcode is cb30af.
Thank you. I am also hoping to book a train to Cambridge from Ely.
What day and time would you like to travel?
I need to leave for Ely sometime after 8:30 on Saturday.
I have the TR3177 train leaving at 09:50 on Sunday, would that work?
I actually need to leave on Saturday. Is there something leaving at a similar time? 
How about TR0718? It leaves at 09:50.
That would be perfect, can you book that for one and give me the reference number please?
Okay I've done that for you. Your reference number INEQVBMN.
That is all I need today. Thank you for all of your help. 
You're quite welcome, have a lovely day! Enjoy Cambridge!
Thank you, have a good day!
its been our pleasure to serve you.
