Huh? I really can't comment on Polish or Arabic, but Spanish is considered to be one of the "finer" cuisines out there. Spain is an incredibly diverse country culinarily speaking. Look at chefs like Ferran Adria and what he can do with Spanish ingredients. Even Anthony Bourdain has declared his love of Spanish food.

I don't think it follows when you say the foods are not great, thus they are not globalized. In the US there are not a lot of native Spanish, Arabs, or Poles, certain concentrated areas not withstanding.

I am not Spanish, but there are few or any cuisines I consider to be superior to that of Spain.
