I need an information on a train from Cambridge to Ely, please.
There are several trains from Cambridge to Ely. What day and time would you like to travel?
I would like to travel on Saturday and get to Ely by 21:30. 
The latest train will get you there by 20:17. It departs at 19:50. It is train TR6698. Would that work for you? 
Can you tell me the price and travel time for that please?
It will cost 3.52 pounds and takes 17 minutes total. Would you like to book it?
No, I am also looking for a cheap restaurant in the centre.
We have several cheap restaurants in the center of town. Do you have a specific cuisine in mind?
I'm looking for something that offers light bites.
We don't have any locations that meet those specifics. Would you like to try for a different type of cuisine?
How about asian oriental?
I highly recommend J Restaurant.  It has great prices on Asian Oriental food and is in the center of town.  Would you like me to book you a reservation?
Yes please.  I need to book for 4 people on the same day.
What time would you like your reservation for?
I'd like to book it for 12:15 please.
Alright, I have your reservation booked at J Restaurant at 12:15 PM for 4 people.  Confirmation number is  ZB5SJ467. Is there anything else you might need?
May I also have the reference number please? 
Your reference number is ZB5SJ467.
Thanks so much for all of your help.
Thank you for choosing Help Desk. Good Bye.
