This neighborhood cevichería is one of Barranco’s most beloved lunch spots. Extremely informal, the bare-bones interior reflects the Argentina-born owner’s love of fútbol, with every spare inch of wall space emblazoned with logos and flags and old match photos. The “Singing Frog” is known for its excellent seafood and large portions. There are more than a dozen types of ceviche, served in heaping bowls with purple onions, choclo (maize), and slices of camote (sweet potato). Many linger here for hours, ordering snacks like conchas a la parmesana (scallops on the half-shell with melted Parmesan) and clay pots of langostinos al ajillo (shrimp with garlic), washing it down with pitchers of beer or chicha morada (a juice made from purple corn).
