i need a train out of cambridge after 17:30
I'd be happy to help. What is your destination?
I'd like to get to London King's Cross on Thursday.
The only option we have is the TR6595 which leaves at 19:00. Does thatwork for you?
Yes, please book it for 5 people.
Your reference number is STVHW0DA.
Can you locate a Starbucks Coffee near the train station in London King's Cross?
There is one 3 blocks from the station,is there anything else ?
I am also looking for a cheap place to stay that has wifi. 
Ok.  There are 10 cheap places with wifi.  Were you looking for a certain part of town?
It doesn't matter, but I want it to be zero stars.
El Shaddai gets zero stars and so does the City Centre North B and B.
Which one of those is the cheapest?
It appears they about the same price. 
Ok please book El Shaddai for 5 people and 4 nights starting sunday
Booking was successful.
Reference number is : BV84E4XA. What else can I assist you with?
That is all I need today. Thank you for your help.
Have a wonderful day. If there is anything else just let me know.
