Sigh. Dining Plan. WDW needs seating capacity, to use a crass term for it, and “Italian” is a safe bet.
While I like your ideas on something Asian, as I think Thai food would absolutely explode in this country if people gave it a chance (my not-so-cosmopolitan town in Florida has three excellent choices, and none struggle for business), most people still find it “weird.”
Sticking to theme, seafood is out, as the Flying Fish Cafe as that covered. I would suggest Spain. It’s interesting, hasn’t been done to death, would’ve gone well in that location with minimal renovation. Close enough to other Mediterranean cultures that it’s not weird. Definitely a wine culture, so revenue possibilities there.
