I need to find a train leaving Cambridge on Wednesday.
I'd be happy to help you find a train. What is your destination?
I am looking to go to norwich.
I have many trains for you. Did you have a departure or arrival time in mind? 
The train should arrive by 21:30
TR7855 will arrive at 20:55 if that works for you
That sounds goo. Can you book for 4 people? 
Your booking was successful. The total fee will be 70.4 GBP and your reference number is K82OYK3I. Can I help you with anything else?
I am also looking for a restaurant on the east side of town. 
There are several to choose from. The Grafton Hotel Restaurant serves classic British fare, but is on the expensive side. Does that sound good or were you looking for something else?
Yes it sound good, can you book table for 4 people at 16:30 on Wednesday?
Booking was successful. The table will be reserved for 15 minutes. Your reference number is: 57035G2J. Is there anything else I can help you with?
That's it. Thank you for your help.
Enjoy your train ride and dinner!
