I need to book a train leaving from London Kings cross.
What day were you wanting to travel on?
I need to leave after 11:30 on tuesday. I'm traveling to cambridge.
I have 6 entires. TR3456 leaves at 13:17. Does that work for you? 
Yes can I get the price on that?
Yes, it's 23.60 pounds per ticket. 
Can you find me a restaurant that serves afghan food and is located in the east?
I'm sorry we don't have any Afghan restaurants in the east area. Would you like to try a different type of food or a different area?
How about Italian food?
The only Italian place in the east is Pizza Hut Fen Ditton. Would you like more information?
i want to book a table for 4 people at 21:00 on the same day as the train.
Your reservation is all set! Your reference number is EV3K4Q4D. Is there anything else I can help you with?
That is all thank you goodbye
Okay great. I'm glad I could be of help.
