I need a train departing Cambridge that will arrive by 17:00.
I would be happy to help you find a train leaving Cambridge. In order to better help you can you let me know where you are traveling to, and what day you are looking to leave?
I am going to Norwich and I want to leave on Thursday.
TR1584 arrives by 10:55.  That should give you plenty of time.
Okay, can you please make a booking for 8 people?
Yes I was able to make a booking and your reference number is 2IFP2I1S.
Perfect! Can you also find me a restaurant?
What type of restaurant are you looking for?
Modern Eclectic please
I'm afraid I could not find a modern eclectic restaurant. Would you be interested in a gastropub?
No, but an expensive Mediterranean place in the center of town would work.
What price range? I have a few options for you.
Something in the upper range, over 20 a place.
There are two Mediterranean choices: la mimosa or shiraz restaurant. Which one do you prefer?
I've heard great things about La Mimosa.  Can you book a table for all of us at 10:00 on the day we arrive?
Table for 8 at La Mimosa on Thursday at 10:00. The restaurant will hold your table for up to 15 minutes. Your Reference number is : F56UFR10.
Thank you for booking that for me. 
Have a nice day, goodbye!
