Yeah I think you're right, we visited in it's last days as the Grill (they had already changed the interior at this point), but I don't think it ever re-opened as Italiano when the park did.I’m fairly sure it never even opened to the public as Italiano. Short lived to say the least!
Safari Pizza and Pasta do a much fuller menu now so it makes sense.
I always though the Grill was a much better offering (menu wise) as it served a range of dishes.
