I need to find a restaurant in Cambridge called the Golden Wok please. 
I have found a Golden Wok at 191 Histon Road Chesterton.
Great, can you please book a table for 2 at 19:30 on Monday?
Yes, I will book your table for 2 at the Golden Wok on Monday at 19:30, would you like a reference number? 
Great, thank you, yes I would like a reference number. If the booking fails, I would like to try for 18:30 instead. 
I was able to book a reservation for 18:30 on Monday. Your reference number is YT9NB9YW. Can I help you with anything else?
Yes I need a train for Tuesday that arrives by 19:15.
Where do you need this train to pick you up?
I'll be going from cambridge to broxbourne.
I have 14 trains that match your preferences, leaving one minute after the hour every hour starting at 05:01 and ending at 18:01.  Which train would you like to book?
I need on that arrives by 19:15 please 
The TR7656 leaves at 09:01 and arrives by 10:01. Is that okay?
Yes that should be fine, thank you for your help.
Is there anything else I can do for you today?
Yes, I need the travel time and departure time of the train.
The train departs Cambridge at 09:01 and the travel time is 60 minutes.  Your train will arrive in Broxbourne at 10:01.  Can I help you with anything else?
Actually, could you check to see if there is a train that will arrive by 19:15 rather than 10:01. I'd really prefer the earlier arrival.
10:01 is 9 hours,14 minutes before 19:15, so it's definitely an earlier train. If you would like to arrive closer to 19:15, though, there is a train that arrives at 19:01.
I think that could be okay
TR5484 is the train that arrives by 19:01. Would you like to book it?
No thank you. I just need the the departure time and the travel time, please.
TR 5484 departs Cambridge at 18:01 and take 60 minutes to get to Broxbourne.
Thank you very much.
Is there anything else you need?
No, I think that covers everything. Thanks for all of your help.
You're welcome. Have a nice day.
