Se7en will be going to Japan to open a restaurant franchise.

In the beginning of 2011, Se7en and his colleagues opened a restaurant franchise called 'Yul Bong Jjim Dak' in Gangnam. He later opened 4 more stores and was very successful.

However, he also went overseas to Japan and opened a store in Osaka and Tokyo. On the day of his opening in Japan, over 1,500 people came.

The reason his franchise was such a success was not only because he was an idol star, but the quality taste of the food. His store was already known in Korea for its great taste. Many Japanese fans had come to Korea to taste his food and had fallen in love with it. Many Japanese fans had requested that they open one in Japan as well.

The store's traditional steamed chicken is made very spicy with peppers that suit the Korean taste. It seems that this spicy food is also a favorite in Japan as well.

Se7en also helped in creating the recipes for the food as he was opening a restaurant with his name and his image.
