Hi, I'd like to book a train to stansted airport from cambridge. Can you help?
Absolutely. Where will you departing from?
From Cambridge, which is why I asked the Cambridge TownInfo centre.
What day would you like to leave? 
On Saturday.  Is there a train that will arrive by 15:15?
There is! TR7213 leaves at 05:40 and arrive at 06:08 it is 10.10 pounds. Can I book that for you?
No need to book it. Thanks. But can you help me find a cheap restaurant in the south? 
Sure - The Lucky Star serves Chinese food and Nandos serves Portuguese food. Do either of those sound good?
The Lucky Star sounds good. That's all I need.
Would you like to book a table?
Can you also tell me the postcode?
 Sure. The post code is cb17dy.
Thanks for your help. Good bye.
You're welcome. Please let me know if you need anything else.
