What train should I take to get to Cambridge by 14:45?
Could you be more specific on where you are departing from and what day you want to travel?
Depart from london liverpool street and should leave on monday.
Any arrival time in mind?
Yes, 14:45. Could you give me a departure time that meets my criteria?
Yes, TR7040 leaves at 11:39 and arrives by 13:07. Would that work for you?
I don't know yet. Do you know how much it will cost? 
Tickets are 16.60 pounds
Okay. I am also looking for a restaurant. Are there any restaurants in the centre that serve asian oriental food?
There are several choices. Do you have a specific price range?
Nah. Can you just book me a table at your favorite one? 2 people at 20:45 on Monday, please.
I was not able to book a table at 20:45. Would you like to try another time?
How about 19:45 and give me a reference number
One moment while I try to make the reservation for 19:45. 
I would like the reference number if it s successful please.
The reference number is 2DNK6C4B.
Thank you very much for the help. Good bye!
Thank you. Goodbye.
