Can you help me find a train headed to Cambridge on Sunday?
I sure can.  Where will you be boarding?
I'm departing from London Liverpool Street, and my train needs to leave after 12:30. 
I have a few options, do you have an arrival time in mind?
I would like to leave london liverpool street after 12:30.
I would recommend train TR6578
That's great can you book it for 8 people?

Awesome. I also need a Hungarian restaurant in the centre, please. 
I don't have any Hungarian restaurants in the centre. Would you like to try another type of cuisine?
Sure. What about modern European?
Would you like a specific price range?
No, I'm not really particular about the price. Any modern european restaurant would be great.
I would recommend Riverside Brasserie.  It's a moderately priced modern european restaurant located in the centre.  Would you like me to make a booking for you?
Yes please, same group of eight, Sunday, 16:45.
