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.

Wedged between two fridge cases near the cash register at Kamala Kitchen, one of New York City’s few Kolkata-style restaurants, is a bookshelf stocked with Bengali magazines and self-published volumes. It functions as a mini lending library for Bengalis who visit the restaurant. “We are very socially active and we have lots of friends,” says Anup Datta, who runs the place with his wife, Debjani, and their son, Aritra. “We once had the conviction that we knew all of the Bengalis in this area. Once we opened Kamala Kitchen, we realized we only knew about twenty percent.”

Lisbon’s Rua do Forno do Tijolo may only stretch a few blocks, but it packs in the city’s full story: French bakers, Portuguese wine bars, Goan curries, Macanese dishes, and old-school coffee roasters, all side by side.

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.

When longtime locals discuss contenders for “best all-around po’boy shop in all of New Orleans,” R&O’s is usually an integral part of the conversation. Fans of the stalwart seafood house located a literal stone’s throw from Lake Pontchartrain will wax poetic about a wide variety of the menu’s delectable standouts – Italian salads studded with tangy chopped giardiniera, oversized stuffed artichokes, seasonal boiled seafoods – before they even start talking po’boys. However, once the conversation turns to the city’s signature long-sandwich, the accolades come in fast and strong. Want a classic shrimp, oyster or soft-shell crab po’boy? They’ll arrive overstuffed, crunchy and fried to juicy perfection.
