Ricardo Manuel Pires Martins likes to brag about the popularity of his bar among Japanese tourists. We don’t begrudge him that, because if you’re in the market for seafood, particularly the less-cooked kind, as these tourists evidently are, Adega Pérola is your bar. Tucked on a commercial lane a few blocks behind the Art Deco condo-and-hotel jam that is the Copacabana beachside, Rio's Adega Pérola sticks close to its Iberian roots, with wine jugs lining the high wall shelves and a selection of about a hundred tapas stewing in their respective marinades behind the glass bar window.

From the street, Café Lamas looks almost intentionally nondescript. A fluorescent-lit bar with a glass case of snacks and a few metal chairs would make it identical to any other lanchonete (snack bar) across the city, if it weren’t for the shadowy doorway behind the bar’s aisle. Behind that door awaits a blast from the past. Café Lamas is Rio de Janeiro’s oldest restaurant – a respectable 138 years old in a city that is rapidly putting on a new face as it buzzes with Olympic, hotel and condominium construction – and the place radiates a sense of history and tradition. Bow-tied waiters politely bend as guests enter the dining room, which is dimly illuminated by lamps on ornate cast-iron mounts.

Although there are plenty of bars on Copacabana’s famous Avenida Atlântica – or even at the beach, at the so called quiosques – very few are worth a visit. Many are just tourist traps. Others are much too expensive. No, the really good bars in Copacabana are inland, along Barata Ribeiro street. That road, along with some of the side streets that let onto it, reveals the true face of Copacabana's popular gastronomy. One of the first bars you encounter on Barata Ribeiro is Galeto Sat's. Open seven days a week, always until 5 a.m., the bar is a bohemian temple – but it’s far from being only that. For many cariocas, Sat's serves the best galeto in town. A galeto is a very young chicken (no more than three months old) cooked over a big coal-fired grill.

In a city with no shortage of postcard views, Bar Urca’s may get the title for most picturesque in Rio. The eponymous residential neighborhood where the bar is located faces Guanabara Bay, where a colorwheel of boats and yachts bobble on the slow waves leading up to the seawall. Across the bay, the iconic Christ statue watches over everyone from atop Corcovado peak behind the neighborhood of Botafogo.

For a city whose natural beauty is what often sweeps visitors off their feet, Rio’s historical gems often look a little like urban ugly ducklings next to the bikini crowds and chic bars on sandy Ipanema beach. That’s a shame, because Rio Antigo has a great story to tell. Old Rio runs along the Guanabara Bay rather than the open Atlantic, and it was the former that gave the city its name – River of January – when Portuguese explorers came upon it in the first month of 1502.

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.

There’s one thing about the very popular Copacabana bar Pavão Azul that remains a mystery, even after 60-odd years of business: its name. Pavão azul means “blue peacock” in Portuguese, but even the owners don’t know where this curious name come from. Some customers who have been frequenting the bar since it opened in the 1950s say that it was named after the bar in the movie “Casablanca” – except that that place was actually called the Blue Parrot. What’s not a mystery is the bar’s popularity. Once just a regular old botequim – a small bar serving simple food – Pavão Azul was discovered by food critics thanks to its patanisca.

If you go to Rio’s Café Lamas to see where leftist organizers met during Brazil’s military dictatorship, go to Majórica to eat steak where the city’s business and political elites gather today. Located on a residential street in Rio’s Flamengo neighborhood, the restaurant from the outside looks like a three-story house, but for the neon red cursive sign with its name. It was founded in 1963 by two brothers from the Spanish island of Majorca. When we last interviewed the owners in 2015, it was being run by the daughter of one brother, together with (then) 79-year-old Galician-born Ernesto Rodriguez, who worked his way up from being the restaurant’s janitor back in 1965.
