Hi, can you point me to an expensive restaurant that serves Italian food?  I will be in the area soon.
I have 4 in the centre of town and one in the south, any preference?
Yes, I would like to book a reservation in the south for 2 people on friday afternoon.
Could you give me a more specific time for the "afternoon"?  Reservations can be placed starting on the hour and every 15 minutes after.
Yes. I actually need a restaurant in the centre for three people on Wednesday at 18:15. 
I cannot get a table reserved for you at that time. Perhaps another day or time slot maybe?
Can you try 17:15?
I was able to book stazione restaurant and coffee bar the reference number is 95K25VSO
Thank you. Can you book me a train arriving the same day as I am going to the restaurant? 
I would be happy to help if I have some more information. What are the departure and destination locations?
I'm coming to Cambridge from London Liverpool Street.
When would you like to leave or arrive by?
I would like to arrive by 10:00 and I would like to book it for the same quantity of people as in the restaurant. I also would like the reference number.
Ok, I have booked 2 tickets on TR5936 leaving Liverpool St at 07:39 and arriving in Cambridge at 09:07. Reference number 68JD5L35. It will be 33.20GBP at the station. 
Thank you! Goobye.
You're welcome. Have a nice day.
