I'm going to say Jakku, because despite Tatooine supposedly being this backwater planet, everyone has been there and they apparently have regular transport service. So it must not be as miserable.

My guess is that spicy cuisine has this masculine bragging aspect to it, so that would suit the warrior culture of Mandalore. As a non-spicy eater myself I'd be more impressed if a culture made incredibly savory cuisine one could actually taste.

I guess it depends on definition of hotness. Certainly Lando Calrissian is one of the smoothest operators.

Also, I came across this post recently of various SW related questions that I thought I'd pass along: https://nondenomifan.dreamwidth.org/32317.html
