I am looking for places to go in town. 
We have many options to choose from, is there a particular type of place you are interested in seeing?
Somewhere in the Centre, entertainment. 
There aren't any attractions of that type in the Centre unfortunately, do you have an alternative preference?
I could also go to a college instead.
What about Christ's college? it's free to get in.
Can you give me the address for Christ's college please?
Sure, it is located on Saint Andrew's Street, postcode cb23bu.  Admission is free.  Can I be of further help today?
Yes, I need a train coming from Ely on Friday.
There are 10 trains fitting your criteria. Do you a time preference on arrival or departure?
Yes, it will need to leave after 12:30. I'll just book it for one person to cambridge.
Train ID TR9236 leaves at 13:35 and arrives in Ely at 13:52.  Would you be interested in booking that option?
Yes. I need to book for one. 
Okay, your reference number is 1A7ZKZ7F. Is there anything else you need?
That is all. Thank you for your help.
Thank you for contacting Cambridge TownInfo centre.  I hope you have a pleasant trip!  Goodbye!
