I am looking for a Saturday train departure from Cambridge
What destination would you like me to look for?
I'm hoping for a train to bishops stortford after 21:15.
There are 2 trains that fit this request. One at 21:29 and another at 23:29. Did you want me to book one of them for you?
Yes please book the train for 23:29. 
How many tickets do you need?
I don't need a booking, but can you tell me the train ID, travel time, and arrival time of that train?
TR0123 is the train ID. It leaves at 23:29 and arrives at 24:07. Did you need any more information about the train?
No, but I need to find a restaurant. It should serve vietnamese food and it should be in the north.
Unfortunately, I'm not seeing any Vietnamese restaurants in the north. Would you like to try a different area or type of cuisine?
How about a Chinese restaurant. Ideally expensive.
Hakka and The Hotpot are both expensive Chinese restaurants on the north side of town. Would you like a table at one of these?
I'd like to reserve a table for 3 at The Hotpot for 10:00 Saturday. I'll need a reference number as well.
I've booked that for you. The reference number is ZAV4B1D8. What else can I help you with?
That'll be everything. Thank you!
