Run by a Harry Potter and coffee fanatic, the aptly named Félix Felicis & Co offers some pretty magical brews. “It was named for my son Felix and my taste for Harry Potter,” barista and co-owner Natalia Montoya told BuzzFeed. “The choice of potion was not coincidental, it has a point: if you do it well, it works perfectly; if you do it wrong, the result is catastrophic – and that applies to the hour in which one makes good coffee,” she said. They offer Colombian coffee in all the familiar forms: espresso, flat white, cappuccino, latte, macchiato, piccolo latte, mochaccino, iced latte, and cold brew. They also have almond milk, a rarity in Buenos Aires. Félix Felicis & Co just opened a second site in the Museum of Architecture, located at Avenida del Libertador 999, on the corner of Callao.
