U: I want a train out of Stevenage on Saturday.

S: Alright, did you have a certain destination in mind?

U: I want to arrive by 11:30 at Cambridge.

S: There are three trains, one arrives at 6:43, one at 8:43, and one at 10:43, which would you like to book?

U: The one arriving at 10:43. I just need 1 ticket and a reference number please.

S: Great! I've booked your trip on Saturday leaving Stevenage and arriving in Cambridge at 10:43. Your reference number is 5CWS7ER4. Is there anything else I can help with?

U: I also would like to find an italian restaurant to eat at in the west.

S: There are two options. Prezzo is moderately-priced and La Margherita is cheap. Would you like me to book a table for you at one of those?

U: Do either Prezzo or La Margherita have a Caprese salad that is a good value for the money?
S: La Margherita has high quality food but too expensive. Prezzo has tasty food and much cheaper to order.
