I need to get to cambridge after 19:30
There are more than 300 trains that arrive in cambridge after 19:30.  What day were you looking to travel and from where?
I'd be leaving from London Liverpool Street on Saturday.
Yes I have a train leaving from Liverpool Street that will arrive in Cambridge at 19:39. Would you like me to book that for you?
How long is the travel time, and what is the price for that train please?
Sure, the travel time is 88 minutes, and the price is 13.28 pounds. Would you like to book it, if so how many riders will there be?
No that's OK, I'll book it later if I need to. Can you tell me anything about a lodging place named "A and B" something?
Sure. It's called a and b guesthouse, found on 124 tension road and is in the moderate price range.
I'd like to go ahead and book that for 1 person, 4 nights starting on Saturday night. I will need the reference number once it's made.
You have been successfully booked and the reference number is L1M02MWF.  Can I help you with anything else?
No, indeed. That will be all. Thank you.
You are welcome. Have a very nice day.
