I think it's in Episode 8 when the Roommates decided to look for the spiciest food to feed Sora, who never sweat while eating hot dishes. They went around and Gayeon, Nana, Seho and Seojun went to this restaurant in Seoul for the famous spicy jjamppong!
Like revealed in the variety show, this one was actually recognized by Star King, and other programs. I think it was rather amazing how they really have the spiciest jjamppong when I cannot even tolerate a regular one.
During the filming of the show, the cook challenged the Roommates that if they can finish the large bowl fully, he will give away jjamppongs to customers on the following week. And LOL they did, and so the free jjamppongs happened. :p
To see more about the restaurant, you can visit this blog.
To get there, one has to take the subway to Singil Station and then go for quite a long walk to the main site. For more detailed directions, please do drop a comment and let's see what I can do to help. :)
