As the seafood hub of a town that loves seafood, Noryangjin market in Seoul, South Korea, sees plenty of aquatic action. Daily seafood auctions take place in the wee hours of the morning between 1 and 6 a.m. every day, and while not as cutthroat or exciting as the wholesale tuna auctions that take place across the sea in Tokyo's Tsukiji market, it's still no place for the faint of heart or the open-toe-shoed.
Founded in 1927, Noryangjin Fish Market moved to its current Central Seoul location in 1971. Walking down the chilly aisle at 5 a.m. as the wholesale auctions are wrapping up but before the retail customers arrive in throngs is probably the best time to go, though I've heard the relative calm of the afternoon affords you more time to poke your way through the cavernous space. You've still got to watch yourself as you pick through the 700+ individual stalls or you're likely to get flopped in the face by a flying flounder or sprayed by a splashing spinefish.
