I'm just looking for a cool place to go later.
Which area do you want to go to?
I would like to visit a college, what would the entrance fee be?
Almost all of them are free. Christ's college is famous and free. What part of town do you prefer?
I don't prefer a part of town. I need to find a train to get there. Can you help me with that too?
Yes, when would you like to travel?
I would like to leave on tuesday.
Christ's college is located in Centre. Where will you be departing from on Tuesday and what time?
hold the phone. what is the entrance fee for christ's college?
Christ's College is free admission. 
Great I also need a train departing from birmingham new street and arriving by 18:15
I'm sorry there are no trains that fit that criteria. Would you be able to arrive any later?
Are you sure? Can you please check again for a Wednesday train from Birmingham New Street to Cambridge, arriving by 18:15?
I am sorry I cannot find anything for those specifications
I find it hard to beleive there are no trains arriving by 18:15. It doesn't need to arrive AT 18:15 just before that. Please check again.
