This is the second largest seafood market in Asia and it is an absolute must visit. There are countless vendors selling all kinds of fresh seafood, and just walking around and exploring is so much fun. Surprisingly, the market is quite clean and does not have that strong fish smell. They do a great job keeping it pleasant.
The best part of the experience is choosing your own seafood and having it cooked upstairs in the restaurant area. Prices are regulated across the market, so you do not need to worry about getting ripped off. Just pick the vendor with the freshest fish that catches your eye.
We went with a Russian king crab, octopus, rockfish, and a few clams. All were live and incredibly fresh. The process is seamless. The vendor takes your seafood upstairs, you get seated, and they prepare it just how you like. The upstairs eating area is massive with great views. We of course added some soju and beer to make somaek.
They charge a small cooking fee of around 15000 to 25000 won, or about 10 to 20 dollars, which is well worth it. Honestly, it was one of the best meals we have had in Korea. Fresh, delicious, and such a fun experience. Highly recommend.
