On the March 9 airing of tvN's 'Youn's Kitchen 2', Park Seo Joon served a couple from Denmark. As 'Youn's Kitchen 2' is filmed from Garachico, Spain, the two asked if 'Youn's Kitchen' is a Spanish TV show. Park Seo Joon explained it's a famous Korean program that you can also search up on YouTube. 

The male customer then asked Park Seo Joon for his name and the actor showed the customer his Instagram. The customers expressed shock at how Park Seo Joon had 4 million followers. 

The lady said, "I'm from Denmark and it has 5 million people living there" and the guy commented, "You're the most famous person I ever met."
