I'm going to be in town and am looking to book my departing train out of Cambridge.  Can you let me know the times of trains on Sunday? 
What is your destination?
Stansted Airport I need to be there by 13:15. 
I have train TR5985 arriving at 13:08 is that okay?
That would be great - can you give me the price and departure time?
The departure time is 12:40. Do you just need 1 ticket booked?
No I still need the price.
The price is 8.08 pounds. Would you like to me book a seat?
No, I'll do that tomorrow.  Could you help me with some places I could visit in the town centre?
We have many attractions in the town centre. Do you have a specific type of attraction in mind?
I just want somewhere to spend some quality time with family.  Do you have a recommendation?
Yeah, I would suggest the old schools.
Which one would you suggest?
i said old school. its entrance is free.
Can I have the postcode?
You got it. The postcode for old schools is cb21tt
Thank you that is all I needed. 
You are welcome. Thank you for contacting Cambridge TownInfo centre regarding trains and attractions. Goodbye.
