U: I need a train departing Cambridge that will arrive by 17:00.

S: I would be happy to help you find a train leaving Cambridge. In order to better help you can you let me know where you are traveling to, and what day you are looking to leave?

U: I am going to Norwich and I want to leave on Thursday.

S: TR1584 arrives by 10:55.  That should give you plenty of time.

U: Okay, can you please make a booking for 8 people?

S: Yes I was able to make a booking and your reference number is 2IFP2I1S.

U: Perfect! Can you also find me a restaurant?

S: What type of restaurant are you looking for?

U: Modern Eclectic please

S: I'm afraid I could not find a modern eclectic restaurant. Would you be interested in a gastropub?

U: No, but an expensive Mediterranean place in the center of town would work.

S: What price range? I have a few options for you.

U: Something in the upper range, over 20 a place.

S: There are two Mediterranean choices: la mimosa or shiraz restaurant. Which one do you prefer?

U: Which of these has a selection of high-quality drinks?
S: Shiraz has some negative reviews on the drinks with customers saying they're average and strange. La Mimosa doesn't have any negative reviews. Would you like to know more about them?
