Eggslut COEX is a burger restaurant at COEX in Gangnam-gu, Seoul, near the COEX Station plaza. It serves American-style burgers with scrambled egg and a patty, along with potato and egg dishes called sluts. The Fairfax, its signature item, puts soft scrambled egg, onion and cheese in a brioche bun, while the slut pairs potato and egg with a thin slice of bread. The interior is decorated in a current style, and a line forms during meal times.
