Task-oriented dialogue about: restaurant

I'm looking for a British restaurant, in the expensive price range.
We have several options available. Is there a certain area of town you're looking for? If not, I recommend Graffiti in the west.
Graffiti sounds good. I'll need a table for four on Thursday at 16:45, please.
It is all booked, reference number is S3Q9J1KJ
Great! Thanks a lot. Thats all I will be needing. Have a good day. Bye!
You're very welcome. Goodbye!
