I'm going to Cambridge and I need a train that arrives by 16:00.
Where will you be departing from and what time will you be leaving?
I will be departing from stansted airport and I want to leave on thursday
OK, the TR3076 train arrives at 15:52. Would you like to book that one or consider other options?
Yeah, book that one.
How many tickets would you like me to book for you?
i want to book for six people. i also want a restaurant. The restaurant should serve northern european food and should be in the centre
I have made the train reservations your reference number is HHQDGA03.  
Thank you. I'm also looking for a restaurant that serves northern european food in the centre. 
I have several options what price range were you looking for?
How about northern european?
I'm sorry, I was mistaken. I do not have a Northern European restaurant in the centre of town.
Okay, how about italian food?
Yes I have 9 to choose from. What price range would you like?
Probably cheap would be best
There are several to choose from. There's Pizze Hut City Centre, Ask, and also Zizzi Cambridge. Does one of those sound good?
Can you pick one for me? 
Absolutely! I really enjoy Zizzi cambridge. Would you like me to make a reservation there for you?
Sure. Sounds good. I need to book it for the same group of people on the same day at 20:15. Can I please have the reference number as well?

Thanks for your help! That is all I needed today.
May I look anything else up for you?
That is all I need today good bye.
Thank you goodbye.
