Ido is a Japanese restaurant in an alley next to Sindang Jungang Market in Seoul that serves aged hoe and seafood dishes. The aged hoe has a chewy texture and savory flavor like live-fish hoe, and the rockfish (ureok) jjim is prepared in a Chinese style. The open kitchen shows the fish being aged, and the maeuntang (spicy fish stew) arrives full of broth in a large aluminum pot. There is also flounder and rockfish (ureok) sushi.
