S: I can get you there at 16:44, if you like. TR8860 will depart cambridge at 14:01. Would you like to book tickets on that train?

U: No. I require the travel time, price, and train ID.

S: That's Train TR8860. Travel time is 163 minutes. The ticket costs 75.10 pounds. Can I help with anything else?

U: I'm looking for a place to dine, preferably an Indian restaurant.

S: I found 22 restaurants, do you have a preference of area or price range?

U: I'd like something cheap and in the centre, please.

S: I have three locations fitting those criteria. The Kohinoor, The Gandhi, and Mahal of Cambridge. Should I book you at any of these locations?

U: Which one is in the best location?
S: All of the restaurants are described as beeing in a nice, convenient location. Would you like more information about one or all of them?
