There's no menu posted and not even a listing for it on the Disney site. This usually means it won't be coming anytime soon. Usually there's first a listing with no menu, then a menu, then sometimes only booking in person or walk-ins and then online ADR booking. If there's no listing, it's anyone's guess. I'm keeping my eyes open for it as I'm also keen to try it. It actually looked last week like it was still under construction.
