I think people would go nuts over kawaii food. Especially since most is just rice & a meat. It’s not too different than Satu’li’s menu, just with the food molded and colored.
you’re probably right though, as they feel they have to dumb down everything for American tourists (in particular American theme park tourists). But I think they should give theme park goers a little more credit. And knowing how much they love bringing “insta worthy” items to the parks; it’d be right up there with butter beer and Lard Lads.
