Editor’s note: As of this week, Rio de Janeiro joins Culinary Backstreets as our sixth city. We’re thrilled to have expanded to four continents, and are looking forward to sharing with readers our explorations of this exciting city's dynamic food scene. Like many things in Brazil's beachside, party-hard Carnival city of Rio de Janeiro, gastronomy has a hedonistic edge to it.

The eyes of Tacacá do Norte’s harried staff widen as yet another customer arrives during the lunchtime rush. The bedroom-sized snack bar can barely hold one line of chairs around its bar but they have somehow managed to squeeze in two. Impatient regulars shake hands and whistle “psst” to the young men staffing the establishment, who gingerly hand steaming pots of shrimp soup and freshly puréed juices over the packed bar.

It might have become one of the more fashionable places in Rio for a caipirinha, yet the simple name of this father-son joint – “Portuguese Kiosk” – suggests humility. Indeed, the pair got their start a decade ago in one of the numerous huts that line the city’s beaches. While the majority of their competitors served the tasty, tried-and-true Rio basics – traditional caipirinhas made with cachaça; beer, and French fries – to sandy-toed beachgoers, Manoel Alves wanted to offer something different.
