Greetings, I am looking for a museum to visit on the west side of town.
You can find the cafe jello gallery at 13 magdalene street and it's free! 
Can I get the postcode for that museum please?
Cafe jello gallery's post code is cb30af.
I'm also looking for a train that goes to Birmingham New Street and leaves on Saturday
Where are you leaving from?
I am departing from Cambridge and would like to be in Birmingham New Street by 20:45 at the latest.
The earliest train available is train TR4975 which departs at 5:01 and arrives at 7:44. Can I book that for you?
A later train would be better, what trains arrive around 20:00?
The closest arrival to 20:00 is TR2815, departing at 18:01 and arriving at 19:44. There is also one arriving at 20:44. Would that be preferable?
What is the departure time for the one arriving at 20:44?
That would be train TR5867 departing at 18:01 and arriving at 20:44. Would this work better for you? I can help you book this one if you like. 
That won't be necessary. Thank you for your help that is all I need today.
Alright, have a nice day.
