Spoodles is closing definitively on August 2 and I've seen recent reports that said (1) the site will be closed for a "minimum of 2 weeks" and that (2) Kouzzina will open in late summer (not fall as previously reported).
If I had to take a wild guess, I'd say Kouzzina will most likely open sometime in the month of September or early/mid-October. We are figuring there's an outside shot we'll be able to eat there on our September 5-14 vacation but are not getting our hearts set on it.
But no, no official opening date has been announced ... in fact it's not even on Disney's website yet, unlike Paradiso 37.
