When you think of Seoul, your mind probably jumps straight to sizzling platters of pork belly or steaming bowls of kimchi stew. But let me let you in on a little secret: South Korea is a peninsula, and Seoul is a city deeply obsessed with the ocean. The seafood scene here is nothing short of spectacular, blending centuries-old fermentation techniques with fiery, modern flavor profiles that will leave you dreaming about your meal for months long after you have flown home.

Wandering through the neon-drenched streets of the Jung District, especially around the bustling alleys of Myeongdong, the salty, briny scent of the sea cuts right through the crisp city air. This isn’t the place for timid eating. Dining on seafood in Seoul is a wildly interactive, sleeves-rolled-up kind of experience. You’ll be cracking shells, wiping spicy red chili sauce from your lips, and clinking chilled glasses of soju with your tablemates. If you want to eat like a true local and experience the absolute best the ocean has to offer without leaving the capital, I’ve got you covered.

Myeongdong Restaurant The Sic-ddang Tucked away on the second floor in the heart of Myeongdong, The Sic-ddang is a high-energy establishment that has mastered the art of bold, unapologetic flavor. With a phenomenal 4.6 rating from nearly 1,800 reviews, this is where you go when you want a feast that hits every single pleasure center. They are legendary among locals for their nakji bokkeum—spicy, charcoal-grilled octopus that arrives at your table glistening in a smoky, fiery red glaze. The octopus is incredibly tender, carrying the unmistakable char of a roaring fire. But what makes The Sic-ddang truly special is how they balance that heat. They are famous for their extravagant set menus, which often pair that blazing octopus with rich, buttery whole lobsters and—surprisingly—gorgonzola pizza meant for dipping into honey. It sounds delightfully chaotic, but it works perfectly. You alternate between the sweet, pristine meat of the lobster, the fiery kick of the octopus, and soothing bites of cold noodle soup. It’s a loud, cheerful, and deeply satisfying experience that captures the dynamic essence of Seoul's dining culture.

Korean restaurant Suragejang Soy marinated Crab Just a short walk down Myeongdong 10-gil, you will stumble upon a true masterpiece. An unbelievable 4.9 rating from over 1,500 reviews tells you almost everything you need to know about Suragejang, but actually tasting their food will change your life. This is a temple dedicated to ganjang gejang—raw swimming crabs marinated in a deeply complex, aged soy sauce broth brewed with aromatics. If you have never had raw marinated crab, prepare for an absolute revelation. The meat takes on a sweet, jelly-like texture that melts the second it hits your tongue. But the real star of the show is the rich, bright orange roe. In Korea, this dish is affectionately known as a "bap-doduk" or "rice thief" because the salty, umami-packed brine forces you to eagerly consume bowl after bowl of steamed rice. The ultimate insider move? Take a scoop of warm, purple-tinged multigrain rice and mix it directly into the empty crab carapace, scraping the edges to soak up every last drop of the golden tomalley and sweet soy sauce. It is an intensely savory, luxurious experience that represents the pinnacle of traditional Korean seafood.

Before you lace up your walking shoes and head to the Jung District, keep a few practical tips in your back pocket to ensure smooth sailing.

Best Time to Visit: The streets of Myeongdong transform into a shoulder-to-shoulder sea of humanity by 7:00 PM. To avoid the longest lines at these popular second-floor havens, I highly recommend aiming for an off-peak meal. A slightly late lunch around 1:30 PM or an early dinner at 5:30 PM is usually the sweet spot.

Reservations: Walk-ins are entirely possible and quite common, but you should expect a wait, particularly from Friday to Sunday. If you're tech-savvy, using a local waiting app like CatchTable can be a lifesaver, though simply showing up a bit early and putting your name on the physical waitlist at the door works just fine.

Price Expectations: Seafood pricing in Seoul covers a wide spectrum. For the fiery octopus and lobster set menus at The Sic-ddang, you're looking at a very approachable 20,000 to 35,000 KRW per person, depending on how extravagant you go. Raw marinated crab at Suragejang commands a higher premium, typically ranging from 35,000 to 50,000 KRW per person. Given the sheer quality of the crab and the painstaking labor required for the fermentation process, I promise you it is worth every single won.

Seoul’s seafood culture is meant to be deeply felt and fiercely enjoyed. It’s about getting your hands a little messy, embracing the heat, and sharing unforgettable flavors with the people across the table. So, bookmark these exceptional spots, grab a friend or two, and throw yourself into the deep, briny waters of the South Korean capital. There is an entire ocean of flavor waiting for you in those bustling second-floor dining rooms—don't hesitate to dive right in.
