I want a train out of Stevenage on Saturday.
Alright, did you have a certain destination in mind?
I want to arrive by 11:30 at Cambridge.
There are three trains, one arrives at 6:43, one at 8:43, and one at 10:43, which would you like to book?
The one arriving at 10:43. I just need 1 ticket and a reference number please.
Great! I've booked your trip on Saturday leaving Stevenage and arriving in Cambridge at 10:43. Your reference number is 5CWS7ER4. Is there anything else I can help with?
I also would like to find an italian restaurant to eat at in the west.
There are two options. Prezzo is moderately-priced and La Margherita is cheap. Would you like me to book a table for you at one of those?
La Margherita is perfect for me, please book me a table at that one.
What day and time would you like the table at La Margherita?
Saturday at 15:15. 
I was unable to book a reservation at La Margherita for Saturday at 15:15. Is there another day or time that you would like?
Could you see if there's anything at 14:15?
The booking was successful . Your reservation number is C9SBUT9T. Is there anything else I can help you with?

No, that's it.
Okay, Thank You. Goodbye.
