Big Tail is a cocktail bar in the Dongmyo alley of Jongno-gu, Seoul, serving drinks that range from classic cocktails to unusual ones. The Old Fashioned has a heavy aroma, the Irish Coffee comes with a fire show, and the Detroit pizza is loaded with cheese and has a crisp edge. Live performances are held on Friday, Saturday, and Sunday, and reservations are taken by phone or Instagram DM. The 3L mega-size cocktail is a menu item meant to be shared.
