U: I am looking for a train leaving from broxbourne and going to cambridge.

S: Sure, when will you be traveling?

U: It will be on Saturday.

S: Do you have a particular time you would like to leave?

U: We would need the train to leave after 12:00.

S: There is a train that leaves at 12:32.

U: That will be fine I need the train ID and price please.

S: Sure the train ID is TR7768 and the cost of the journey is 14.32 pounds.

U: I also need a place to dine in the centre that serves seafood.

S: The Loch Fyne is the only available restaurant in the centre that fits your criteria but it is an expensive place to dine, will that be alright?

U: Do they have non alcoholic drinks?
S: Unfortunately, one of the drawbacks of the Loch Fyne restaurant is that they offer a limited selection of non-alcoholic beverages.
