U: Hello, I'm trying to find a train that goes from Cambridge to London Kings Cross. Can you help me book a ticket?

S: I can help with that. Can you tell me what day you will be traveling?

U: I need to leave on Saturday after 18:45.

S: The soonest departure time would be at 19:00 on saturday, is that okay?

U: Yes, that's perfect. Can you book that for 8 people?

S: You are all booked with reference number 144VDBRM.  The cost of 151.04 GBP will be payable at the station.  Can I be of further assistance today?

U: I'm looking for an expensive place to eat in the centre, what is there that fits that criteria?

S: There 33 places that fit your criteria. Do you have a particular cuisine type in mind so that I can narrow the results down?

U: It doesn't matter what kind of food. What would you recommend for a large group of 8 people?

S: How about don pasquale pizzeria?

U: Are the meatballs served here well-reviewed?
S: No, quite the opposite as those who have previously dined at the Don Pasquale Pizzeria regarded the food as poor and wouldn't recommend.
