user: I'd like some places to go. Some sort of entertainment.

assistant: There are 5 places all in the east, south, and west. Which of those areas would you prefer?

user: I prefer the centre area. What do you have for places to go? Type of college maybe?

assistant: There are 13 colleges in the centre area. Many of them are free - I would suggest King's College or Trinity College.

user: On second thought, I'd rather go to a entertainment spot. Got any of those?

assistant: 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.

user: 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?

assistant: The postcode of corpus christi is cb21rh.

user: I also need to find a train leaving Cambridge on Friday and arriving in Peterborough.

assistant: There are quite a few trips available. What time do you want to arrive in Peterborough?

user: I'm not picky on when I want to arrive I just want to leave after 12:45.

assistant: 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?

user: Yes, book it for seven people. I'll need a reference number.

assistant: 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?
