I want to find a Chinese restaurant in the centre of Cambridge. 
There are 10 choices and we have cheap, moderate and expensive options, any preference?
I would like a suggestion of a moderately priced Chinese place. 
I recommend Jinling Noodle Bar.  It's located at 11 Peas Hill City Center.  Would you like me to book a table for you?
Yes can you please for three at 17:00.
On what day would you like your reservation?
Can you book it for me and get a reference number ?
What day would you like to dine on ?
I want a reservation for 2 people at 17:30 on thursday. Sorry, I don't know why I said the other thing before that. I must be going crazy.
Your table was booked. Your reference number is 42XEDGDF. Is there anything else I can help you with?
I also need a Friday train to Broxbourne. 
Certainly. Will you be departing from Cambridge? What time would you like to leave after or arrive by? There are departures every hour from 5:01 through 23:01.
I would like to leave Cambridge after 15:45.
The next train after 15:45 leaves at 17:01 from Cambridge. Would you like to book this train?
Yes, please book it and provide the reference number.
How many train tickets would you like to book?
2 please and I need a ref. number.
Okay, booked it and your ref. is TJGHMT3I. 
Thanks, that's all I needed today. Goodbye!
Thank you. Let me know if there is anything else I can assist you with.
