U: I'm looking for a train to go to cambridge on tuesday.

S: I am happy to help with that. Can you tell me where you would be leaving from?

U: From London Kings Cross and I need it to leave after 18:15.

S: I have 3 trains available. They leave at 19:17, 21:17 and 23:17. Would you prefer one of those?

U: I'd like to book the 19:17 train for 8 please and need the reference number.

S: I was successfully able to book the 19:17 train for 8 people.  The total fee is 188.8 GBP payable at the station.  Your reference number is L0TQ4FD6.

U: I will also need a place to dine. I'm thinking something cheap, after that. Maybe Portuguese food?

S: There are two cheap Portuguese restaurants located in the city, the Nandos and Nandos City Centre. Would you like to book a table with either of these?

U: Are there any interesting sights visible from the dining room?
S: Overall, Nandos City Centre is slightly better regarded for their views than is Nandos. The views at both places, however, are very dependent upon which table you are seated at.
