Task-oriented dialogue about: restaurant

I could really use something to eat.
I have over 100 restaurants to choose from, would you mind narrowing down your search for me with perhaps a food type or price range?
Expensive restaurant in the centre, please.
Any particular type of food you're hankering for?
Not really. Which is your favorite? I'll book that for 13:00 Thursday. There will be 6 of us.
I'm sorry, I have not found anything for that time yet. Can you choose another day or time please? Are you sure you don't have a preference for food type?
Let's try to book it for 12:00 then for 6 people on Thursday. I'll also need a reference number.
Which restuarant do you want to book at?
I'm not sure. Just something expensive. We are celebrating.
I booked you at Curry Queen. Your table will be reserved for 15 minutes. Reference number is C06RJUNL .
Thank you for your help. This is all I needed.
You're welcome. Please come again if you need more help.
