I'm looking for an expensive restaurant to dine at, somewhere in the North End of the Cambridge area. 
There are 5 expensive restaurants on the north side of town. What type of food would you like?
Any type of food is fine. Can you book a table someplace that sounds good? I need a table for 4 on tuesday at 19:30.
I have booked you a table for 4 on Tuesday at 19:30 at Saigon City, on the north end of Cambridge at 169 High Street Chesterton and your reference number is JARZR20Q if you need to contact them between now and then.
Thanks! I also need to book a train leaving Cambridge on Wednesday.
I have many trains leaving from Cambridge to London kings cross on Friday. What time would you like to book the train for?
Uuh... actually, I'm headed to norwich from cambridge on Wednesday.
Sorry about the confusion on that, what time would you like to depart?
I would like to leave after 12:00 please, what do you have available?
I have many different times available. The first one leaves at 12:26 followed by 13:36, 14:36, 15:36, and so forth until 23:36. Which time would you like best?
12:26 should be okay can I please get the train ID and travel time?
I apologize see that the TR5574 leaves Cambridge for Norwich Wednesday at 12:36 and arrives at 13:55. Will that work for you? 
Thank you for that information, that is all I need at this time.
I'm glad I was able to help! Thank you for using the Help Desk. Have a great day!
