I'm planning a trip to Cambridge and I'm looking for a train that leaves sunday and arrives at 5:30. 
There are three trains that meet this criteria, two from Birmingham New Street at 22:40 and 23:40, and one from London Liverpool Street at 23:39. Which do you prefer?
i would like the 22:40
Sure, that is train TR1873.  Would you like me to book some seats for you?
No thanks. I will book later. But can I get the price and travel time please? 
Sure, TR1873 is 60.08 GBP per ticket and is a 163 minute journey.  Is there anything else I can do for you today?
Yes, I need to find a restaurant that serves indian food in the centre of town.
I have several options. What price range would you like? 
Could you give me a recommendation?
How about The Ghandhi located at 72 Regent Street?
That sounds fine. Can you book me a table at 10:45 on Sunday?
Ok, how many people will you be dining with?
I only need a booking for a party of 1.
I am sorry that time is unavailable. Would you like to book for another day or time?
How about 09:45 instead?
I am sorry that time is unavailable as well. Would you like to book for another day or time?
How about 9:45?
