I am looking for an expensive restaurant that serves British food please.
I have found 6 restaurants for you would you like a specific area of town?
No, it doesn't matter.  Can you reserve one of them for Sunday at 13:00?  I will be dining alone.
Alright, I got you a table at the Graffiti. The table will be reserved for 15 minutes and the reference number is: FAVAELU5. Do you need the address or phone number?
No, that is all I need, thank you. 
Great. Have a great day!
