I'm looking for a train leaving Cambridge. I need to arrive at 15:30.
There is a train leaving Friday at 13:59 that will get you to London Liverpool street at 15:27.  Will this work for you?
No, I need one that leaves on Sunday.
If you'd like to go to London King's Cross, there are 104 trains that match your specifications. What time would you like to leave at?
I would like to go to London Liverpool Street for 8 people.
Great, your reference number for the 8 tickets is: U9G8K0GF. Anything else I can help you with today?
I am looking for a place to dine that serves vietnamese food in the west.
I found Thanh Binh they serve Vietnamese food in the west part of town.
I need a cheap place to eat, does that restaurant fit that criteria?
Yes, Thanh Binh is a cheap place to eat. Would you like me to book a reservation?
Yes, please. I need a table for 8 at 11:30 on Sunday. And may I please have the reference number?
OK, your reservation is booked, your reference number is RQ5HR7PY.
Great thank you for your help that will be all
It's been a pleasure, thank you.  Enjoy your visit!
