U: I need a train to Cambridge and I need it to leave after 12:45.

S: There are 833 trains that meet your needs. Would you like to narrow it down by departure station and/or day of travel?

U: I'm leaving from peterborough and need to travel on tuesday.

S: That narrows it down to 23 choices. What time were you wishing to arrive?

U: Arrival time doesn't matter, it just needs to depart after 12:45. I'll need to book the travel for 8 people. Are there any that can accommodate that many?

S: The TR4679 departs at 13:19. Booking was successful for 8 people, the total fee is 132 GBP payable at the station. Reference number is : GVI45XUY.

U: Thanks, I'm also looking for a restaurant that serves European food in the expensive price range.

S: I have 5 results for european restaurants.  Do you have an area preference? I have results in the north, west and town centre.

U: I have no preference.  I would like to book at a table today at 21:00.

S: How about eraina? I can book you a table there if you like.

U: Do you know if it has various non-alcoholic drink options?
S: A couple reviews that went to Eraina said there was limited amounts of non-alcoholic drinks there. But one person said there were tons of variety to pick from.
