I'd like some places to go.  Some sort of entertainment.
There are 5 places all in the east, south, and west. Which of those areas would you prefer?
I prefer the centre area.  What do you have for places to go?  Type of college maybe?
There are 13 colleges in the centre area. Many of them are free - I would suggest King's College or Trinity College.
On second thought, I'd rather go to a entertainment spot. Got any of those?
I apologize but in that area, there are no entertainment spots.  That is mainly the church area. Perhaps I can look in a different section of the city for you.
Ok, I'd like to stay in the city centre.  I guess a college will do.  Can you give me the postcode for one that you would recommend?
The postcode of corpus christi is cb21rh.
I also need to find a train leaving Cambridge on Friday and arriving in Peterborough.
There are quite a few trips available. What time do you want to arrive in Peterborough?
I'm not picky on when I want to arrive I just want to leave after 12:45.
There are many options leaving after 12:45. The earliest departure after `12:45 is 13:06, arriving by 13:56. Would you like to book that option?
Yes, book it for seven people. I'll need a reference number. 
The tickets are booked and the price is 115.5 GBP which you will pay at the station. Reference number is 9YGZEA87. Can I help you with anything else?
No thanks. You have been very helpful. Goodbye.
You are quite welcome! Have a good day!
