U: I need to book a train

S: I can help you with that. Where are you headed?

U: I am going to Cambridge.

S: Great, can you tell me where you will be departing from and which day you want to travel and at what time?

U: I will be leaving from London Liverpool Street going to Cambridge on Sunday.

S: There is a train that leaves at 5:39 would you like me to book it for you ?

U: Yes please, just for one person.

S: Your booking was successful. Your reference number is DWZMV9KS.

U: Thanks! Now can you help me find an expensive gastropub restaurant in the centre please?

S: There are two that meet your criteria. The Backstreet Bistro, and The Slug and Lettuce. Would you like me to book one of those for you?

U: I'm looking for some steamed mussels that aren't far too expensive.
S: The Slug and Lettuce has reviews stating the prices are the best they've seen in awhile. Would you like to know more about them?
