Rod is at his seat at the end of the bar, his booming Scottish voice subdued by the spirited dim of a couple dozen Friday night regulars speaking mostly English in a variety of accents. We make our way to the steam table in the corner of the room to find it empty. Looks like there may have been chicken wings in there. If you want to munch free food at the weekly happy hour at Betsy’s Hotel bar, you have to get here at 6 p.m., when it starts.

La pizzaiola, played by Sophia Loren, peddles pizza from a counter on the doorstep of her street level apartment. She kneads dough while crying out for custom in a thick dialect and as clouds of flour fall to the cobbled Neapolitan street. This scene comes from one of the great cinematic homages to a city: Di Sica’s L’Oro di Napoli (“The Gold of Naples”), a 1954 a film that grapples with the bittersweet tastes of comedy, tragedy, hustling and the art of making do. There’s nowhere better to see Naples in all its “golden” glory than in the very neighborhood in which the film’s star, the inimitable Totó, grew up and where parts of the film are set: La Sanità.

The kids were playing in the park, and Dad needed a cup of coffee for the caffeine boost to keep up with his daughter. Luckily there was a café nearby – where you would least expect one. The park is a modest little playground patch in a residential neighborhood across from the funicular that hauls people up and down Mtatsminda Mountain to the amusement park and restaurant above the city. The café is on the ground floor of a Communist-era apartment block, just a couple dozen paces away. It was everything a little coffeehouse should be: warm, cozy, quiet and wheelchair accessible.

In Greece, where the land is mostly rocky and steep and the climate hot and arid, the olive tree thrives, and for millennia, olive oil has been as essential to Greek cooking as the gnarled, silver-leaved trees have been to its landscape. Greece is the third largest producer of olive oil in the world after Spain and Italy and the greatest in consumption per capita. Used liberally as a cooking fat for all manner of ingredients and preparations, as well as in its raw state to dress or flavor dishes, olive oil also plays an influential role in Greek baking, such as in koulourakia, twisted or coiled cookies, and paximadia, the twice-baked rusks that come savory or sweet.

One of the things we love about Japanese food is that it celebrates specialists. A good sushi chef makes only sushi, and only after years of study to learn the art of making the perfect rice. Likewise, only a master of the dynamics of hot oil can craft perfect tempura. So it’s no surprise that at Japanese chicken restaurants one can find a true dedication to specific methods of preparing fowl.

Lisbon is a city that knows how to keep a secret. In the early days of World War II, German, American and British spies overran the capital – Portugal was officially neutral during the war – and many of the city’s bars and casinos were hotbeds of international (in)discretion. Later, just before the Carnation Revolution in 1974, many central cafés were meeting points for covert leftist associations. Today, the hidden bars in Lisbon are decidedly less cloak-and-dagger. Yet there is still a real sense of intrigue when you ring the bells of exclusive clubs, private cultural associations and former brothels, and step inside for a hush-hush drink.

When we talk about the “suburbs” in Brazil, some may imagine the affluent outer boroughs of London, New York or Singapore. But in Rio de Janeiro, they’re nothing like that. Far from its beautiful beaches, Christ the Redeemer and Sugarloaf Mountain, the city’s suburbs are the opposite of tony – they’re where Rio’s working-class people live. Yet the suburbs are where you can find the most authentic carioca soul. They are home to the biggest favelas, the most important samba schools, Afro-Brazilian religious temples, the majority of football fields and, of course, the best botequins, or local bars.

There’s something special about Crete, Greece’s biggest island. The country’s most fertile region, it has a long history of food and wine production that stretches back to the Bronze Age, making Crete one of the most interesting culinary destinations in Europe. Bordered by the Aegean Sea to the north and the Libyan Sea to the south, the island is home to over 70 different edible herbs and wild greens, and local farmers produce a wide range of products, from Mediterranean staples like olives, tomatoes and eggplants to more tropical produce, such as mangoes and papayas.

Sants is a working neighborhood with an industrial past and a communal present, both of which it proudly flaunts. There are the street names – like L’Espanya Industrial, Carrer Wat (dedicated to the engineer James Watt) and Vapor Vell (Old Steam) – that tell the story of industrialization in Catalonia, and the two buzzing municipal markets and the many bodegas and restaurants, like Terra de Escudella or Bodega Salvat, that serve as meeting points for an engaged community. Although shaped by a diverse set of international influences, the neighborhood’s sophisticated culinary scene is tied together by something more local: vermut culture.

In the 1975 short film Gvinis Qurdebi (Wine Thieves), four mischievous villagers sneak into a stingy neighbor’s wine cellar, crack open his kvevri (enormous ceramic urn) and start drinking the wine stored inside. As they get drunk and rambunctious with toasts and song, they wake the winemaker who ends up joining them. It is in this same spirit of Georgian joie de vivre that Avto Kobakhidze, Givi Apakidze and Zaza Asatiani have come together to take other people’s wine and sell it under their own label, Wine Thieves.

A sweet warmth lies just below the surface of Condesa’s über-cool Angelopolitano. Walking through the front door, we were first struck by the restaurant’s elegant decor, which exists somewhere between hipster chic and business casual. Potted plants sitting beneath framed 19th-century photographs make the space feel more like an art gallery than a place to eat. Such an environment would be off-putting if it weren’t for the staff, who flashed big smiles as we entered and spoke to each other in a familial, teasing tone you’d more expect to hear at a friend’s dinner party than an upscale restaurant.

When we first discovered this delightful ouzeri in Neo Psychiko last May, we were thrilled to have found a place that specialized in Politiki Kouzina – not the cooking up of politics but the cuisine of Constantinople, often called simply I Poli, or The City, by Greeks even today. Ironically, mutual friends had chosen it to fete a Turkish guest, a visitor from Istanbul, which seemed a culinary version of taking coals to Newcastle. But she pronounced the fare delicious, and smacked her lips over such shared dishes as Imam Baildi, dolmades and bourekakia made with phyllo.

First-time visitors to Astek probably step in for the same reason most people convene at a reputable Istanbul meyhane: Good conversation in a cozy setting over a few cold glasses of rakı, together with fresh melon and white cheese, and perhaps a hot appetizer or two once the anise-based spirit has succeeded in seriously stimulating the appetite. And while one is unlikely to be displeased with any of Astek’s fine offerings, the head waiter and manager Mehmet Akkök is the reason why regulars return. Mehmet Bey brings to the table an exuberance and keen sense of professionalism that comes with years of service in the sector he loves.

For 2,000 years, people have flocked to the Abanotubani baths, whose hot sulfuric waters have long been fabled to possess magical healing qualities. The Persian king Agha Mohammad Khan soaked there in 1795, hoping to reverse the effects of the castration he suffered as a child. He dried off, found his conditioned unchanged and razed Tbilisi to the ground. While people continue to espouse the curative properties of the sulfur baths, we can only vouch for their powers to relieve stress, loosen up sore muscles and help poach the hangover out of you. It is the latter attribute that inspired the local chef Tekuna Gachechiladze to open a restaurant last year that might not cure erectile disorders, but is definitely designed to nurture alcohol-stricken bodies back to life.

The ascendance of Spanish gastronomy has largely had a Basque signature, which, together with the Catalan scene, is seen as the vanguard in Spanish haute cuisine. But while Nouvelle Basque has gotten all the spotlight lately, the food culture of this northern region has always been outstanding, thanks to its abundant rains and a territory that encompasses the Cantabrian Sea and Ebro River. Basque taverns are largely known for their pintxos, a kind of tapas that are more sophisticated in taste as well as in design. At certain times of day these small plates fly nonstop out of the kitchen, usually chosen at the chef’s discretion.
