I am looking for a train leaving from broxbourne and going to cambridge.
Sure, when will you be traveling?
It will be on Saturday. 
Do you have a particular time you would like to leave?
We would need the train to leave after 12:00. 
There is a train that leaves at 12:32.
That will be fine I need the train ID and price please.
Sure the train ID is TR7768 and the cost of the journey is 14.32 pounds.
I also need a place to dine in the centre that serves seafood.
The Loch Fyne is the only available restaurant in the centre that fits your criteria but it is an expensive place to dine, will that be alright?
I would like to book a table for 2 at 17:45 on Saturday.  What is the reference number please?
I was able to book it, reference number is A1ZSFEZ5.
Thank you. I appreciate the assistance.
Is there anything else I can do ?
That will be all! Thank you!
Have a fantastic day, goodbye!
