@james @ljsThings like "German thing," "Czech thing", "British thing," or "Korean thing" are inherently full of stereotypes and do not encompass all aspects of a culture.
But tourists often want to experience (and even purchase) these stereotypes because they encapsulate the stories of many people in that culture had to endure.
For example, Korean Kimchi has evolved throughout history, and the current recipe includes chili powder after the introduction of chili in 19th century in Korea, during war.
But if you replace the chili powder with something else that was not available in Korea, it's not "Korean" because it does not reflect its historical roots.
