Ramyun Brothers in Japan

Kang Ho-dong, Lee Seung-gi, and Bae In-hyuk are gathered to open a ramyeon restaurant in Japan. The three of them are serious when it comes to cooking ramyeon. However, coming up with new recipes and doing business is something new to them. They are full of passion, but still, they have a lot to learn. Finally, the restaurant is open, and customers come in. How will their first day of business go?

Various customers visit Ramyun Brothers to check out Korean ramyeon for the first time! The dishes for the first day are Donghaemul Ramyeon, Jinguk Hwangtae Ramyeon, and Massis-jeyuk Ramyeon. Will they be able to show the teamwork of Ramyun Brothers? At the end of the day, they will reveal the votes and comments from the customers, and it will change the fate of Ramyun Brothers. How will it turn out?

Another day of selling and promoting the K-ramyeon has come. However, things are not as good as the first day due to a storm that ruins the weather. Since they have to let go of the Jinguk Hwangtae Ramyeon and the Masiss-jeyuk Ramyeon, the brothers come up with new menus. A Japanese noodles expert visits the shop. The brothers become nervous and wait for his honest opinion.

After receiving a "Could Be Better" vote on a menu, the third day starts with a brand new ramyeon. But unlike the previous days, the restaurant is packed from the start. People from the area and other cities visit Ramyun Brothers up to the point that they are all lined up outside. Bewildered by the sudden increase, the brothers have to decide whether to extend their working hours or not.
