I need to catch a train in Broxbourne on Wednesday.
What time would you like to leave Broxbourne?
I need to arrive in Cambridge by 17:15 please.
There is a train arriving in Cambridge by 7:32.
Train ID please and thank you 
I'd suggest TR5972, it departs at 15:32 arrives by 16:32. It costs 17.90 pounds per ticket. 
Thank you I also would like a place to eat in the centre that serves afternoon tea food.
No record match your search, can I try anything else?
How about one that serves international food?
I have the varsity and the bloomsbury restaurants when would you like to book
I would like to book at Varsity for 5 people around 20:45 on the same day I arrive.
No problem!  I have a table booked for you.  Your reference number is KFUNWVWH.  What else can I do for you?
Nothing else for today. Thank you. 
Have a good day!
