Korean cold noodle soup

I tried a Korean cold noodle soup for the first time at Koba tofu grill in Irvine. I asked the server what kind of cold noodle soup they have. He answered something but I don't understand what he said:( anyway I ordered the white cold noodle soup which is in the picture. The soup is lots of sesame flavor and no taste. I was surprised. Then took some salt in the soup and mixed it to spread the salt. I ate
The noodle and was surprised again. It's too salty. I believe the noodle was made with salt already and people enjoy the unbalance of tastes with noodle and soup. Since I got more salt in the soup, totally the taste was salty than the original one. Maybe I don't order this thing again.
