I want to take a train to Cambridge on Friday, what's available? 
I found 202 trains. What is your departure station?
I would like the departure station to be broxbourne. 
I have a train leaving that station at 09:32 and arriving at 10:32, if that's acceptable?
No, I need something that gets there by 9:45.
I have train TR3005 that arrives at 09:32,would that be good for you?
Yes, I need the reference number.   I am also looking for a place to eat in the south area, preferable italian.
There are two restaurants that are Italian, Pizza Hut Cherry Hinton, and Franky and Bennys.  The reference number for your train is  0EG8EWWR.
Pick one of those. I need it for the same amount of people at 17:15 on the same day.
I'm sorry, both of those restaurants are fully booked for the time requested. May I check another restaurant for you?
Okay. Can you find another Italian restaurant?
There are many italian restaurants not in the south of town, do you have another area preference?
Not really. Please make a recommendation.
There is a Pizza Express that is in the Centre area. It is in the moderate category. Would you like me to try to book that?
Yes. It will just me at 17:15 on Friday.
I was able to book it, the reference number is PPXQDNOM.
Terrific.  I appreciate your help.  Good bye!
