Open since 1980; widely considered Korea's definitive ganjang-gejang house. Whole raw blue crabs marinated in a sweet-savory soy brine. Eat the meat, then mix the orange roe with rice in the shell. Open 24/7. There's a spicy yangnyeom version too. Pro Soy Crab's walls are lined with autographs from Korean baseball stars and Hallyu actors who frequent the 1980-founded ganjang-gejang institution.
