I'm traveling to cambridge and I was hoping you could find me a train on tuesday that arrives by 13:30. 
Where would you be departing from? 
I am leaving from Stevenage
There is a train departing Stevenage on Tuesday that arrives in Cambridge by 12:43. Would you like me to book that for you?
When is the departure time?
It leaves at 11:54. Is there anything else?
Yes, Can you book that for me and send me a reference number?
I will book it for you,is there anything else I can do for you ?
I need to find a French restaurant. 
There are two. Restaurant Two Two and Cote. Would you like me to book either of those for you?
Please book Cote for me.
What day would you like to go and at what time? How many people will be in your party?
Sorry, I got ahead of myself. I want a french restaurant but it must be in the moderate price range. Do either of those options match?
They are both in the expensive price range. Would you like to find another?
Yes, search for asian oriental food instead then please. 
How about Yippee Noodle bar, it's the only one that is moderately priced.
What's their address?
Yippee noodle bar is located at 40428 King Street City Centre in the centre area. Would you like a reservation?
No thank you. I am actually all set now. Thanks, and bye!
Have a great stay in Cambridge.
