Hi, can you please help me book a train departing from London King's Cross on Sunday?
We have 10 different trains for that day. Do you want to depart and/or arrive at a particular time?
I want to leave after 9.
There is a train leaving at 9:17, Sunday. Would you like for me to book that?
I need a booking on the train for 7 people to go to Cambridge. Is that doable? 
Yes it is. Do you have a preferred time of departure?
I would like to leave after 9:00. 
I have booked the train for 9:17.  The reference number is BBQXVMZK.  The total for 7 people is 132.16 GBP and is payable at the station. Anything else I can do for you?
Yes, could you please help me find a expensive danish restaurant?
It looks like there aren't any expensive Danish restaurants in town.  Would you like me to look for another cuisine? 
British food would be a suitable replacement I suppose.
We have many to choose from.  Any part of town work best?
No preference. Can you recommend one and book the same group of people on the same day please
Ok, I recommend the the cambridge chop house. It is in the city centre. What time would you like to eat?
i would like the reservation to be for sunday for 7 people at 20:15. 
Booking for 7 was successful. The table will be reserved for 15 minutes. Your reference number is  EXZLQAZY. May I help you with anything else?
Thanks.  That's all.  Goodbye
