I am looking for a train leaving broxbourne.
I can help with that! Your destination will be cambridge I presume, what day would you like to travel?
I would like to travel on a Saturday.
There are hourly trains from 5:32 onward. Did you have a particular time of day in mind?
Yes I want to travel on a Saturday.
Where is your destination located?
I should have confirmed that I am indeed going to Cambridge.
Thank you for confirming that.  One more detail: Did you have a particular time period in mind for your trip?
Yes.  I want to arrive in Cambridge by 21:30.  
TR7846 will get you into Cambridge by 10:32.  Would you like me to book a seat on that for you?
No I don't need to book a seat, but can you tell me the departure time. 
Of course. The departure time for that train is 09:32 with an arrival time of 10:32. It's a 60 minute ride. Anything else I can help with?
I need a place to go in town.
Did you have a specific place or area in mind?
The centre, please.
There are numerous places in the Centre, can you tell me what type if place or activity you would like to do and maybe we can narrow it down?
How about a zoo or art gallery? 
I'm afraid we don't have a zoo, although if you like plants there is the Cambridge University Botanic Gardens. There are several galleries, such as Regency Gallery and Ruskin Gallery.
Are there entrance fees to these places?
The Cambridge University Botanic Gardens are 4 pounds, and the Regency and Ruskin Galleries are free.
Please, I need the address and phone number for the Regency and Ruskin Galleries. Thanks.
The address for the regency gallery is 39 fitzroy street and the phone number is 01223365454. For ruskin gallery it's anglia ruskin university, east road, their number is 01245493131.
One more thing. Would you confirm the attraction type for the regency gallery and ruskin gallery?
The Ruskin Gallery is a museum. Do you need anything else?
That will be all, thank you for your help.
You are welcome. Have a nice day. Goodbye.
