Hello, I am looking for an Indonesian restaurant. Can you help me with that?
I'm so sorry, but I don't see any Indonesian restaurants. Will another cuisine do?
Oh really? Indonesian is the only cuisine I will consider.
My apologies, but there truly aren't any indonesian restaurants listed in all of Cambridge. Would you consider one that serves oriental or indian food?
how about one that serves italian food?
there are 22 of them. what is your price range?
It should be in the cheap price range and in the centre of town.
I have three to choose from. Would you like me to suggest something?
Yes, please. Which would you consider to be the most authentic?
pizza hut city centre is nice
I will try that.
Can I help you with anything else?
Yes, can you get me a table for 3 at the pizza hut?
Sure!  For what day, time and how many do you need it for?
I will be there on thursday at 5 pm. 6 people please. 
Ok.  I was able to get you a table for 17:00.  Your reference number is N5G8UXRG.
I'm also looking for a train. The train should depart from cambridge and should arrive by 08:00.

I want to go to Stevenage, on Sunday. 
The train leaves at 5:00.
Can you make a booking and give me its reference number?
Actually, it's at 5:21. If you still want to take that train, how many tickets would you like for me to book for you?
Yes, 3 tickets please.
