I am looking for a German restaurant in the expensive price range.
There are no restaurant that fit your description, do you want me to look for restaurant with moderate price range?
Did you try the center of town?
Yes, there are not any restaurants available.  Would you like to try a different price range?
How about an expensive Indian restaurant?
Yes, there are several expensive Indian restaurants in the centre area. Curry Garden and Saffron Brasserie and a few others. Should I book a table for you?
book a table for 2 people at 12:00 on thursday.
I have booked you at Curry Garden. They will hold the table for 15 minutes. Your reference number is 8TKID5N6. Do you need anything else?
I am also looking for a train. The train should be on the same day as the restaurant booking and should arrive by 09:45.
Where would you like to depart from and what is your desintation?
I want to depart from peterborough to cambridge.
the tr8272 will get you where you need to go
When does it depart?
It departs at 05:00. 
OK, thanks, I'll take care of it from there.
The price would be 23.60 per person for that train and be 51 minutes long trip.  Enjoy your day!
