I have the TR7187 that will arrive at 01:27. Would you like me to book that for you?
Yes, please book that for me.
For how many people?
Hold on a moment. Can I first make a restaurant booking?
Yes, we can do that after we finish with your train booking. How many people do you need tickets for?
I don't need to book it yet. What's the departure and travel times for the train?
TR7187 departs from Cambridge at 23:59 and arrives in London Liverpool Street at 01:27. Do you want me to book that for you or move on to restaurant assistance?
I really dislike math, can you just let me know the trip duration if you have it in front of you?
Sure. The trip is 88 minutes. Would you like to book a seat?
Yes, and then lets work on the restaurant.
How many tickets would you like?
I don't want to book the train right now. Could you find me a restaurant in centre that serves swedish food? 
There appear to be none in the area. Any other types of food you are interested in?
Is there British food in the centre in the moderate price range?
There are four restaurants that serve british food. I recommend Cotto for you. Their address is  183 East Road City Centre
What's the postcode with that?
The postcode is cb11bg.  Can I help you with anything else?
No thank you, that is everything.
Have a nice day!
