Hi. Can you help me find a train?
Sure, where would you like to go?
I'm going to Cambridge from Liverpool Street. On Sunday.
I have many trains leaving and arriving all day. Do you have a preference for time of travel?
I need to leave after 11:15.
The TR9025 leaves at 11:59 and gets you into London Liverpool Street by 13:27. Would you like to book it?
I need to know the price and travel time please
The train will cost 13.28 pounds a ticket and leaves at 11:59. 
Thanks I'm also looking for a restaurant called Charlie Chan can you find some information for me?
Charlie chan is a cheap chinese reasurant in the centre. Phone number is: 01223361763 postcode :cb21db Address: Regent Street City Centre. Do you need anything else?
That would be all thanks !
Enjoy your meal sir and you are welcome.
