I would like to find a college to visit.
Is there a specific area you would like to visit?
No, just Cambridge in general. I'd also like to know any entrance fees, please. 
Most of the colleges in town have free entrance fees. I'd recommend Christ's College on Saint Andrew's Street in the centre. It has free admission.
Cool, I also need a train ticket leaving london liverpool st and I am going to cambirdge
okay what day will you be traveling and when would you like to leave?
I will be traveling on wednesday after 15:30.
I have one leaving at 15:39 will this work?
Yeah that will be fine can you book this please?
You will need to pay 16.6 GBP at the station but the booking was successful, your reference number is RWDSKR05.
Can you let me know that train ID so I can find it?
The train id is TR7978. Can I help with anything else?
No, that will be all for today. Thank you!
You are welcome, enjoy your stay in Cambridge.
