South Korea has historically been influenced by China, and in recent years by the Western world, particularly the United States. The influence of Western culture and rapid modernization has changed peoples' eating habits as well; many people now enjoy Western and other Asian foods in addition to traditional Korean food. Pizza is one of the favorite foreign foods among South Koreans, though it tends to differ from the pizza served in the west, often featuring corn, sweet potato, mayonnaise, bulgogi and various other ingredients.
