Hi, what can you tell me about a restaurant called hakka?
I can tell you that it's an expensive Chinese restaurant on the Northside. What else would you like to know? 
I need to reserve in for Thrusday. 
I have a lot of options. Was there a specific area you were interested in? How many people would you like to reserve for?
Yes, I would like a reservation at 18:15 on Thursday for two.
Unfortunately, there are no reservations available for Hakka at 18:15. Would you like to book another day or try another time?
Is there an opening at 17:15?
17:15 was successful. You're reference number is EWFXUJB5. Is there anything else I can help you with? 
I also need a train  that leaves after 17:00 on friday departing from cambridge. 
Where will you be traveling to?
I need to go to Birmingham new street.
I have train TR7420 that is departing at 18:01 and arrives by 20:44. Would that be acceptable? 
Yes I would like to book the TR7420.
For how many tickets?
Book for two people. And, may I also have the reference number, please.
