I think you could just ask something like “what are some of your favourite world cuisines excluding the obvious ones?” and then explain what you mean.
Apologies though, I guess this is just because it’s not your first language, what you said makes sense it’s more the connotations of the phrase. I think someone also posted a gif making a similar joke. Probably the best straight up alternative without the connotations would be “world food/cuisine.”
North Korean! Would love to try it but I guess similar to South Korean food?
God of the Dead from Hades!
