I am looking for a train from cambridge to london kings cross.
I see several options, all leaving on Friday. Is there a time you prefer to leave at?
I need to leave after 17:45 on tuesday
There are 3 trains that match your request. They leave at 19:00, 21:00, and 23:00 respectively. Would you like to buy a ticket for one of these?
I'll take the earliest train. I need two tickets and the reference number.
Booking was successful, the total fee is 47.2 GBP payable at the station. Reference number is : 0KAR945K. Anything else I can help with?
I'm also looking for a restaurant. The restaurant should be in the expensive price range and should be in the centre
I have several restaurants located in the centre, what type of food are you looking for?
I'm open to restaurant suggestions. What sounds interesting?
I have 5 restaurant, choices of food are african, asian oriental and british. Which of the  restaurant you?
African sounds good. Can you make a reservation for two for the last seating?
I sure can but in order for me to make a reservation for you at bedouin for some yummy african food, I need a precise time and day
Actually...can you just shoot me the address?
Sure, the address is 100 Mill Road City Centre.  Is there anything else I can help you with?
No. Thank you that will be all. Goodbye
You're welcome, have a nice day!
