Shin Ramyun Black is indeed a good one.
I also like Nongshim Neoguri spicy seafood flavor (available at most Asian supermarkets, and on Amazon). I believe it’s imported from South Korea. I’ll make it according to the package directions, and throw in a few raw shrimp while it’s cooking. Then I’ll boil an egg, and stir fry some vegetables (usually some baby bok choy, broccoli, and mushrooms, with a little soy sauce), and add those on top of the ramen, and garnish with some green onion, and a little sesame oil.
