I haven't had German food in ages so please find me a place in the centre that serves it
I'm sorry, there aren't any German restaurants in the centre, would you like me to expand the search to other parts of town?
Sure, but please make sure there aren't any in the centre again too. 
There aren't any options for German food for any area, I'm afraid. Would you like to try a different type of food?
is there one that serves italian food?
Yes, there is. What's your price range?
Expensive price range and I need a table for 7 at 13:00 on Thursday and the reference number.
your all set reference # is 79REVFJ1. anything else today?
Yes I'm looking for a train to Cambridge that same day.
Ok great. Where will you be departing from?
I will be leaving from kings Lynn.

I just need to arrive by 10:30.
There are 5 trains that will get to Cambridge by 10:30. The earliest departs Kings Lynn at 05:11. The latest one leaves at 09:11.
