I'm looking for a train that runs on Tuesday.
Sounds good, Where will you be arriving from and going to?
I will be departing from london liverpool street and arriving at cambridge. 
I have many travel time to choose from. Do you have a preferred travel time?
I want to leave after 14:45.
The TR5245 leaves London Liverpool Street at 15:39 and gets into Cambridge at 17:07. Would you like me to book it for you?
That sounds great.  Will you make a booking for 5 people please?  And I'd like the reference number for my records. 
Ok   I will book it for you for 6 people
Actually I only need it for 5 people and I will need a reference number.
Booking was successful, the total fee is 83 GBP payable at the station. Reference number is : 7F4OHHP6 Payable at the desk, any other questions today?
Yes, could you help me find a North American restaurant that is expensive.
The gourmet formal kitchen is a great choice. Shall I book it?
