Excellent! What would you like to know?
I need a train that  will leave monday ggo to Cambridge at 12:00

The closest thing I have to your departure time is the TR6226 which leaves at 13:39.
Okay. I also need to find a guesthouse to stay in the expensive price range.
I have 9 guesthouses that fall in the inexpensive category. What part of town do you prefer?
I prefer an expensive hotel in the north please
I don't have any in that area, another perhaps?
How about one in the moderate price range then.
There are 9 places available. Do you have a preference in rating?
I prefer a four star hotel, please. And can you tell me whether one has free parking?
How does acorn guesthouse sound?  It is in the north and moderately priced.
