Hi, I need a train out of Cambridge, thanks! 
Sure, where will you be traveling to?
I will be going to london liverpool street.
There are 70 trains available. Is there a specific day and time you would like to leave or arrive by? 
I would like the train to leave on friday after 15:30. 
TR9956 I believe would be my choice.  Thank you. 
OK, can you book that for 8 people, please?
Booking was successful, the total fee is 132.8 GBP payable at the station .
Reference number is : SEJBN5KV.

Great, can't wait! Are you able to help us find a cheap Chinese restaurant somewhere near the city centre, also?
Certainly! There are 3: Charlie Chan, Rice House, and Golden House. Do any of these sound like they'd be to your liking?
Yes, all of them are.  Can you get a table for all 8 of us at Charlie Chan at 12:15 for the day we travel?
Unfortunately I wasn't able to make that reservation. Is there another date or time you would like me to try?
Could you try 11:15, please? 
I was able to get you at table at charlie chan at 11:15 for all 8 guests.  Your reference number is YZERKJXH.  Anything else I can help with?
Nope, that'll be everything I need!
Have a nice visit
