I need to find a train that will arrive cambridge by 13:45 on friday
sure, where are you departing from?
I'm departing from cambridge and want to go to birmingham new street
the tr7195 will get you there by 12:08 how many tickets please?
Well, first, what is the departure time, price and travel time?  It sounds like it will work.  
Sorry, that was the TR6668, not TR7195, arrives by 12:44, duration of the trip is 163 minutes and the price is 75.10 pounds.
Thank you. Are there any expensive restaurants in the town centre?
There are a variety of options in that area. Is there a particular type of food that you would like?
Not really. Can I just have the postcode and phone number for your favorite place?
