What area would you like to catch a train and what day would you like to leave? There is a train leaving at 19:00 and arriving at kings cross at 19:51 would you like me to book it for you? It's 23.60 pounds.
I want to get a train that is leaving after 18:15. I need to go from Cambridge to London Kings Cross on Tuesday. How much is it? Ok. I also want to book an expensive restaurant in the centre part of town.

I just want to make sure you didn't want me to book that train for you? And what type of food are you looking for?
