I am planning a trip in Cambridge
okay can you be a little more specific? 
I'm looking for a train to arrive by 21:45 on wednesday.
OK, what station would you like to depart from and which station would you like to arrive at?
It would be from broxbourne to cambridge, I will need to book that for two people.  
TR6477 will arrive in cambridge on wednesday by 21:32. I booked 2 tickets. The fee is 25.79 GBP payable at the station. Reference number is 3800N2KU. Wiil that be all?
I also need a place in the centre that serves indian food.
curry garden is expensive, kohinoor is cheap. Do these interest you?
Can you book a table for us at Curry Garden at 13:45?
Sure thing! How many people, what time, and what day?
 book a table for the same group of people at 13:45 on the same day.
Reference number is : 6JOS1HJY. Is there anything else?
That will be all. Thank you.
You're welcome! Have a great day!
Thanks. Goodbye now!
