U: I need a train on Thursday.

S: Okay, I can help with that. Where are you heading to, and departing from.

U: I'm departing from Cambridge and going to Ely. I'd like the train to leave on Thursday and arrive by 15:45.

S: I have 5 trains that can get you to Ely by 15:45. What time would you like to depart?

U: I would like to arrive by 15.45 I want the travel and departure time

S: The most reasonable train leaves at 13:50 and arrives in Ely at 14:07.

U: Thank you. I'm also looking for a restaurant... the kymmoy? Do you have any information about it?

S: The kymmoy serves asian oriental food.  It is located in the centre and in the expensive price range.  Is there anything else you need to know?

U: Is the Kymmoy highly rated for serving large portions?
S: The kymmoy diners have said that the portions were really great for sharing, but others have said that the portion sizes were small, and should have been larger.
