The buy-at-market, cook-next-door system
At Korea's larger seafood markets (like Noryangjin in Seoul or Jagalchi in Busan), the typical process involves buying raw seafood directly from a market stall by weight, then carrying it to an adjoining or upstairs restaurant that charges a separate cooking fee to prepare it for you. This two-step system is standard and not a scam by itself, but it does mean two separate transactions and two separate prices to track, which can be confusing on a first visit.
Market floor brokers and being steered to a specific stall
Some larger seafood markets have informal individuals who approach visitors and offer to "guide" them to a specific stall, sometimes receiving a commission from that stall in a way similar to other broker arrangements -- this doesn't automatically mean a bad price, but it does mean the recommendation isn't neutral. Feel free to browse independently and compare a few stalls' posted per-weight prices before committing, the same comparison habit useful at any market.
Shopping with confidence at a seafood market
- Watch your seafood weighed and confirm the price per weight before finalizing your purchase.
- Ask about the separate cooking fee at the restaurant before you sit down, since this is billed independently from your seafood purchase.
- Compare a couple of stalls if you have time, rather than accepting the first one you're steered toward.
- Keep both receipts -- market purchase and restaurant cooking fee -- until you're satisfied the total matches what you expected.
Language support at the cooking-fee restaurants is generally more limited than at the market stalls themselves, so having a translation app ready, or asking market staff to help clarify the cooking fee and preparation options before you commit, smooths out this second half of the two-step process considerably.
