U: Please help me locate a train that departs from Cambridge and is going to Leicester. Thanks.

S: What time would you like to leave?

U: I'm flexible about departure time, but I must arrive by 18:45 on Saturday.

S: There is a train that will arrive at 18:06. Would you like me to book it for you?

U: Not yet but can I get travel time and train ID?

S: The train ID is TR9193 for that trip. Can I help you with anything else?

U: What is the travel time for the train?  Also, I need a place to eat in the centre.  It should be in the expensive range.

S: I'm sorry that train ID is actually TR7600. The duration of trip is 105 minutes. As to locating a restaurant, what type of food would you like to eat?

U: Any place in the centre with good food and service would be perfect.

S: How about the midsummer house restaurant?

U: Do they have high quality ale?
S: Midsummer House Restaurant does serve alcohol. The ale is tasty and refreshing, and most guests found the drinks to be in the affordable range.
