What good attractions are there in the city centre?
There are over 40 of them, many of which are free; did you have anything more specific in mind?
No, just pick something.  
The Cambridge Contemporary Art Museum is a good attraction that is free. Would you like the address or directions?
Actually, can I get the address and phone number please? 
Sure, it is located at 6 Trinity Street.  The phone number is 01223324222.  Can I help you further?
Yes.  I need to find a train to travel from Stevenage to Cambridge.
Okay, what day and what time would you like to leave? The ride is about 49 minutes and the train comes every two hours.
I need to leave Saturday and must arrive by 20:00.  I don't care what time the train leaves as long as I arrive on time.
I have train TR2442 leaving stevenage at 17:54 and arriving in cambridge at 18:43.  Would you like to book this?
Yes, please. I need 4 tickets.
