As ridiculous as this is (Korean men dress gayer than metrosexuals in the States, and men's cosmetics are taking off as its own industry), Koreans do have a pretty hearty diet versus other Asian countries.  Where I used to live in Itaewon, Seoul, there would be daily buses of Japanese and Chinese tourists who would stop at the shitty overpriced "local" restaurants like it was a pilgrimage to Mecca just for the novelty factor of having (by their standards) extremely large portion sizes.
