Visited Monday lunch, 10 August 2026. Party of twelve, private room. Paid for out of our team’s own pooled budget. No comps, no sponsorship.

Search for the best seafood buffet in Seoul and one name comes back more than any other: Viking’s Wharf, on the second floor of the COEX Convention Center in Gangnam. Unlimited lobster, shelled for you, priced in US dollars at $110 a head.

The short version: it earns the reputation. Not for everyone, and not every day, but for what it sets out to do it is very hard to fault.

I can’t rank every buffet in this city, and I’m not going to pretend otherwise. What I can do is take the best-known candidate apart in detail. I ate here with eleven colleagues, on a weekday, for two and a half hours, and I read every price board on the way in. Below is what $110 buys, what it doesn’t, and the kind of eater it rewards.

For context on the price: my team had been pooling its monthly dinner budget for three months to afford this one lunch. That is where $110 sits for people who live here, and all twelve of us left saying it had been worth doing.

Quick facts

How it compares with Seoul’s other big buffets

Honest framing first: this is one restaurant reviewed closely, not a ranked list. But it helps to know which shelf it sits on.

Seoul’s high-end buffet market is mostly hotel buffets, which spread across every cuisine and treat seafood as one section among many. Viking’s Wharf does the opposite. It is narrow and deep: lobster, sashimi, raw shellfish, a grill, and a dessert counter, with pizza and pasta as an afterthought for people who don’t eat seafood.

That shapes who should come. If you want variety for its own sake, a hotel buffet gives you more range for comparable money. If you specifically want to eat lobster and raw shellfish until you stop wanting to, this format wins, because the expensive thing is the unlimited thing rather than a garnish on a bigger spread.

The other distinguishing feature is that the drink and dessert counters are outside brands rather than in-house approximations, which I get into further down. That is unusual at this price and it is a real part of the value.

Especially good for groups

This is one of the easier expensive restaurants in Seoul to bring a group to, and that is worth saying plainly because group dining here is often a headache.

Two things make it work. There are private rooms, and ours changed the meal: a buffet floor is loud enough that you cannot hear the person opposite, but with the door closed twelve of us could actually talk between trips to the counters. Ask for one when you book. And weekday lunch has no time limit, running as a single 12:00 to 15:00 service, while every weekend seating is capped at 1 hour 50 minutes. With twelve people, queuing at the lobster bar alone eats into that.

The format also solves the usual group problem of nobody agreeing on a cuisine. Everyone walks off to a different counter and comes back to the same table.

How to book if you don’t read Korean

Viking’s Wharf runs on reservations and staff checked our booking name at the door. Three routes:

• CatchTable, the app most Korean restaurants use for timed seatings
• Naver Reserve, via the restaurant’s Naver Place listing
• Phone: 1644-4446

There is a ₩10,000 per person deposit taken at booking and refunded when you turn up. For our group of twelve that was ₩120,000 up front, returned after the meal. Budget for the outlay even though you get it back.

A caveat I want to be straight about: Korean booking apps often expect a local phone number for verification, and I booked through a Korean colleague so I cannot tell you first-hand whether CatchTable or Naver Reserve will complete without one. If you are new here and hit that wall, phoning 1644-4446 is the route that does not depend on an app account. If you get through on either app without a Korean number, I would genuinely like to know.

The price is in dollars, and that matters

Viking’s Wharf quotes in US dollars and converts at the bank’s daily closing rate. A board above the till shows the day’s number in big yellow digits. On my visit, $110 came to ₩155,100, around ₩1,410 to the dollar.

Two consequences. If you earn in won and the won weakens past ₩1,500 to the dollar, the same meal costs meaningfully more than it did for me, worth a glance at the rate the week you book. If you hold dollars, the currency risk disappears, which makes this one of the few Seoul restaurants that is arguably cheaper for someone paying in USD.

Payment is flexible: won, dollars, or a mix, though dollars must be in bills. And the child rate needs proof of age, a passport or Korean medical insurance card. Bring it or you pay adult price.

The lobster: they shell it for you

The Lobster Bar is the reason the place exists. Whole cooked lobsters sit on crushed ice and a staff member cracks and shells one to order, handing you clean meat on a plate. No bib, no mallet, no fighting with claws.

Beside the counter is a dispenser of warm melted butter, plus chilli and cocktail sauces. Take the butter. Tail meat is firm and springy with a clean sweetness; claw meat is softer and saltier. After three lobsters the salt builds up, so alternate: a plate of lobster, then something cold and raw from the shellfish counter, then back.

The dishes twelve people actually talked about

Here is what I did not expect. Past the seafood counters there is a hot section, and the two things our table kept returning to were both on it: sogeum-galbi (소금갈비, salt-grilled beef short rib) and butter-grilled abalone.

Sogeum-galbi is seasoned with salt only, no soy marinade and no sweetness, so it tastes like beef rather than sauce. In a room where you have just paid $110 for unlimited lobster, having the beef station be the most-discussed dish is an odd outcome. It happened anyway.

The abalone deserves a specific note: it appears raw at the shellfish counter and butter-grilled here, and the two versions taste like unrelated foods. Try both.

There is also pizza, pasta, an Asian station, abalone porridge and a truffle mushroom soup. This matters more than it sounds: bring someone who doesn’t eat shellfish and they will not be stuck with bread rolls. That is rarely true at a seafood buffet.

Sushi, sashimi and raw shellfish

The Sushi Bar and Sashimi Bar are staffed rather than self-service. Point at what you want and a chef plates two or three slices per fish. It slows you down, which I suspect is deliberate, but nothing sits warming under a lamp.

The brands inside are not filler

Something I only noticed halfway through: the drink and dessert counters are not the buffet’s own approximations of things. They are actual outside brands, which is unusual and goes some way to explaining the price.

• Starbucks for the coffee, served in Starbucks cups. Unlimited
• TWG for the tea, with its own display and a note about 1837 Black Tea
• Sammontana, an Italian gelato brand, with its own neon sign
• Noah Bakery for the bread and pastry corner
• FIJI Water for the still water
• Moët & Chandon in a separate champagne case
• Zumex, a dedicated press for fresh orange juice

Buffet coffee is normally something you accept rather than enjoy. Getting it in a Starbucks cup at the end of a meal like this genuinely changes the last ten minutes.

Alcohol is not included. It is ordered and paid for separately, we added Asahi draft, which was very good with the lobster and the galbi, but budget for it on top of the $110 if drinking is part of the plan. If it isn’t, the bill is exactly the buffet price and nothing else.

Dessert: the mango is not a joke

I was full and planning to skip dessert. Then I saw the apple mango, cut and laid out on ice. Dense, properly ripe and deep in sweetness, the kind that costs an uncomfortable amount at a Korean supermarket. I went back three times.

Beyond that: gelato, bakery, a case of cakes, coffee. The cheesecake and chocolate cake were restrained rather than sugary, which is the right call at this point in the meal.

COEX or Jamsil? They are not the same price

This catches people out. Viking’s Wharf branches are not priced identically. The Jamsil branch operates as “Viking’s Wharf Heritage,” a premium line, and charges more.

The $20 gap compounds with group size. Two people: $40. Four: $80. Twelve, like us: $240, about ₩340,000, or roughly a month of our team’s pooled budget. Add parking, which is free for three hours at COEX and not discounted at all at Jamsil, and the gap widens slightly again for anyone driving.

So: large group, go to COEX. Two people marking an occasion, Jamsil’s premium room may well be worth it. The unlimited-lobster core is the same at both.

I ate at COEX. The Jamsil figures come from published visitor reports rather than my own visit, and prices move, so confirm before you book.

Practical notes

• Wash your hands on the way in. There’s a station at the entrance and it’s part of the entry routine rather than a suggestion.
• Shellfish allergies: a notice at the entrance states the restaurant does not accept liability for crustacean allergies. Take that at face value.
• Meal vouchers are valid for one adult only, can’t be used for children, and aren’t refundable or exchangeable for cash.
• Pay mid-meal to skip the queue on the way out.

So is it the best, and is it worth $110?

I won’t crown it the best in Seoul on a single visit. What I will say is that it is the most single-minded seafood buffet I have eaten at, and the value maths works out. Eat three or more lobsters and this comes in cheaper than the equivalent à la carte anywhere in the city, with the sashimi, grill and mango effectively free on top. It rewards appetite, so come hungry and it delivers comfortably.

As an occasion it lands. Exposed brick, high ceilings, a wine cellar, a champagne case, and the shell-it-for-you service that removes the one genuinely annoying part of eating lobster. The five things our table kept naming afterwards: lobster, sogeum-galbi, abalone, cake, apple mango. Two of those are not seafood, which tells you the kitchen is not coasting on the headline item.

Go if you have a real appetite, you’re marking something, you’re booking for a group that wants a private room, you’re paying in USD, or you want one big seafood blowout in Seoul without researching ten restaurants.

Think twice if you’re a light eater, you dislike buffets on principle, or the won is trading weakly and ₩155,000+ a head is more than the occasion calls for. Those are real caveats rather than complaints about the food.

Cheapest sensible version: COEX branch, weekday lunch. $20 a head below Jamsil, no 110-minute clock, free parking, and a calmer room than the weekend rush.

While you’re at COEX

COEX absorbs an afternoon if you let it. Starfield Library is a few minutes’ walk inside the same complex and free to enter. If you’ve arrived with luggage, which is plausible given COEX sits between Samseong Station and the airport bus stops, drop it before you eat rather than after. A $110 buffet is not somewhere you want to be minding a suitcase.

Frequently asked questions

Is Viking’s Wharf the best seafood buffet in Seoul?

It is the best known, and it is the most seafood-focused of the city’s high-end buffets: unlimited lobster shelled to order, staffed sushi and sashimi bars, and a raw shellfish counter. Hotel buffets in Seoul offer more variety for comparable money; Viking’s Wharf offers more of the expensive thing. Which is “best” depends on whether you want range or depth.

Where can I eat at COEX Mall?

COEX has everything from food courts to fine dining. Viking’s Wharf, on the second floor of the Convention Center, is the splurge option: an all-you-can-eat seafood buffet at $110 per adult, best suited to groups, celebrations and large appetites.

How much does Viking’s Wharf COEX cost?

$110 per adult and $55 per child (36 months to 12 years), tax included, the same price every day of the week. Because the restaurant bills in US dollars and converts at IBK Bank’s daily rate, the won amount changes daily, on my August 2026 visit, $110 came to ₩155,100.

Do I need a reservation, and is there a deposit?

Yes, book ahead, staff check the reservation name at the door. Reserve through the CatchTable app, Naver Reserve, or by phone on 1644-4446. There’s a ₩10,000 per person deposit at booking, refunded when you arrive.

Does Viking’s Wharf COEX have private rooms for groups?

Yes. We booked one for a party of twelve and it made conversation possible in a way the main floor does not. Ask about room availability when you reserve.

Is the lobster really unlimited?

Yes. Staff at the Lobster Bar shell a whole cooked lobster to order and there’s no cap on refills. Most people find three is the practical limit before the saltiness catches up.

Is there parking at Viking’s Wharf COEX?

Three hours are free per car. Register your licence plate number when you pay or the discount won’t apply. Note that the Jamsil Heritage branch gives no restaurant parking discount at all.

Is there food for people who don’t eat seafood?

Yes: salt-grilled beef short rib, pizza, pasta, an Asian station, soups, a bakery, a gelato counter and a dessert case. A non-seafood eater will still eat well.

Are drinks and alcohol included?

Soft drinks, coffee and tea are unlimited. The coffee is Starbucks, the tea is TWG and the water is FIJI. Alcohol is not included and is ordered separately.

How long do you get to eat?

Weekday lunch is one continuous 12:00~15:00 service with no time limit on your table. Weekend and holiday services run as four timed seatings capped at 1 hour 50 minutes each, which is tight for a large group.

Why is the Jamsil branch more expensive than COEX?

Jamsil operates as “Viking’s Wharf Heritage,” a premium line, at $130 per adult versus $110 at standard branches like COEX. For a group of twelve that’s a $240 difference.
