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.

Autumn in Rio finds the city at its the best. The days are sunny, the scorching heat of January and February has subsided, and it's low season for tourists, which means the beaches are less crowded. The only problem with fall days is they end too early—the sun sets by 6:00 pm in April. If you want to keep the day going, one good option is to head to one of the city's many beachside pé sujos (literally, dirty feet), ultra-casual outdoor bars. On a recent April evening we found ourselves at Bar Bunda de Fora (Bar Butt-Out), steps from Copacabana Beach. According to owner Deborah Cardoso, the bar got its nickname because the interior used to be so small that when customers placed their orders at the counter their rear ends were technically outside the bar. It's a classic low-key Rio joint: the beer is light, cheap, and bem gelada (very cold); the stools are made of plastic; and the food is fried. The crowd is young and old, mostly made up of families and neighbors.

Order a plate of vindaloo in one of the many Goan restaurants around Lisbon and your local friend at the table may point out that the origin of this dish is, in fact, Portuguese. Even the name can be decoded back to the Portuguese vinho d’alhos (wine and garlic), he’ll say. But let’s be honest here, amigo, vinho d’alhos has about as much to do with Goan vindaloo as the croissant does with the cronut. Vinho d’alhos may have sailed off to Goa along with Vasco da Gama in the 15th century, but when it returned to Lisbon with Goan migrants in the 1960s and 70s, something had changed. It had gone Goan.

Portuguese gastronomy is at the core of Rio's botequins, the small, often family-run gastrobars spread all over the city. Traditional botequins offer European food and some unique aspects of Brazilian culture – mix you’ll find only in Rio. That being said, it’s hard to say whether Tasca Carvalho, the brand new Portuguese gastrobar in Copacabana, is a typical botequim. Run by two young Portuguese friends newly arrived from Porto, Tasca Carvalho is not a mix, but 100 percent Portuguese. And that makes it unique in Rio's street food landscape. Perhaps the only indication of Brazilian influence you might find at Tasca Carvalho is in the ambience. The tables and benches, spread all over the sidewalk, follow the carioca rules of informality.

Barcelona’s urban sprawl makes it easy to forget that the city is adjacent to two fertile regions to the north and south, El Maresme and El Baix Llobregat, which provide numerous hyperlocal culinary treasures throughout the year. In spring as in other seasons, these treasures appear at markets and restaurants, their origins proudly displayed, sometimes even with the names of the specific villages that they come from. The coast and gently sloping mountains of El Maresme are home to numerous villages, three natural parks and beaches. Unsurprisingly, there’s an abundance of seafood here, including gamba de Arenys (Arenys prawns), scampi (escamarlans in Catalan, cigalas in Spanish) and little Mediterranean sand eels (sonsos in Catalan).

In terms of greenness, Athens doesn’t even come close to other European capitals with their verdant parks and blossoming gardens. The truth is, modern urban development has not been particularly gentle with this city. Numerous concrete buildings along with poor road design hem in inhabitants and visitors with featureless views. Thankfully, there are some oases in the cement desert that offer the hungry local or tourist a lush respite in which to enjoy a meal or a drink. Just behind the parliament lies the Ethnikos Kipos, or National Gardens, the indisputable green heart of the city.

When Leyla Kılıç Karakaynak opened up a tiny restaurant on Kallavi Street in Istanbul's Beyoğlu district in 1996, she couldn't have predicted that she would end up practically running the whole street. That small restaurant, Fıccın, is now spread across six buildings on the same block-long pedestrian-only street and has become an Istanbul institution. The restaurant shares its name with its signature dish, a meat-filled savory pastry that is among the Circassian specialties on the menu. Karakaynak's family hails from North Ossetia, and while Fıccın serves up a number of classic Turkish staples, it's the regional dishes that you can't miss, including Çerkez tavuğu, a simple yet sumptous paste of shredded chicken and walnuts, and Çerkes mantısı, comforting, pillowy dumplings served under yogurt.

On the left bank of Tbilisi’s Mtkvari River in the Plekhanov district is David Aghmashenebeli Avenue, a thoroughfare long associated with wallet-friendly Turkish restaurants and discount clothing boutiques. Some 15 years ago, the crumbling 19th-century buildings and huge eucalyptus trees that lined the street were crowded with people hawking everything from wooden utensils to costume jewelry, fresh produce and coffee beans labeled “Nescafé.” It was a congested, lively sidewalk bazaar of sorts that exemplified the Asiatic spirit of Tbilisi. However, a massive urban renewal project in 2011 put an end to the colorful disorder. Today, most of Aghmashenebeli is a sensible European-looking boulevard that the former President of Georgia likened to Paris, although the Turkish restaurants are still there serving up tasty Anatolian specialties.

Istanbul's Kurtuluş neighborhood is home to a number of slow-burners, establishments that may be hidden in plain view due to their plainness but that end up becoming some of our favorites. Gimmicks don’t fly in down-to-earth Kurtuluş, where neighborly ties are strong and home-cooked meals are preferred. Tucked on a side street in the middle of the quarter is a small eatery that exemplifies this tried-and-true character. Behind windows that fog up quickly in the winter sit a handful of tables facing an open kitchen in what might be Istanbul's coziest restaurant, Ben-u Sen, which showcases the divine ev yemekleri (home cooking) of the delightful Nuray Güzel.

Cariocas don’t give much love to Niterói, joking that the only reason to go to this city across Guanabara Bay is for its spectacular view of Rio de Janeiro. But while less busy and far less popular than Rio, Niterói is full of lovely beaches, great museums, excellent restaurants and hundreds of bars. Among the many reasons to visit is Salve Simpatia, a botequim – or small, family-run bar serving snacks to go with drinks – where traditional bar gastronomy mixes perfectly with delicious artisanal burgers, specialty beers and remarkably good music, especially samba. Salve Simpatia (which means something like “Hello, my brother” in Portuguese) opened in 2012 and was known only to locals in the Icaraí area for a while.

Jordi Piquer opened his popular restaurant in 1968 on an auspicious day: April 23, a holiday that honors his namesake saint. Saint Jordi must have been looking down on Piquer and his dedicated customers when the restaurateur decided to sell his establishment in 1986: three trusted employees banded together to buy it, keeping the Sant Gervasi neighborhood institution in business. A fine example of a classic 20th-century Barcelona restaurant, Casa Jordi is decorated in the old masía (traditional Catalan farmhouse) style over two floors but adapted to urban dimensions, meaning that there are fewer intimate corners but larger, more flexible rooms with tables for groups.

Convincing someone to accompany you to Istanbul’s Pendik district is no small feat. The Asian-side suburb is located in the far eastern reaches of the city, a trip of at least an hour and a half from the city center requiring no less than three metros and a cab. We've been met with moans and groans upon mentioning the name, as the district is synonymous to many with the wildfire-like urban sprawl that has engulfed Istanbul over the years. Those up for the journey, however, are rewarded handsomely at Lipa, a meyhane serving Bosnian specialties. The neighborhood of Sapan Bağları is home to a large population of natives from Sandzak, a predominantly Bosnian Muslim region now split across modern-day Serbia and Montenegro.

Julian Ramirez started out at the age of 14 as a shop boy at a busy bakery in Colonia Guerrero in 1959, then a bustling blue-collar neighborhood, easily connected to downtown by streetcar. Back then, at La Antigua del Guerrero, he learned the business: wiping windows, sweeping up and eventually making deliveries on his bike. One nibble at a time, he picked up the art of cake- and bread-making from the shop’s master bakers. Those trade secrets would serve him over the next 63 years and beyond as they pass on to his kids and theirs. Many of Mexico’s classic bakeries like the Guerrero operation fell one by one with the introduction of mass-produced bread, tearing at a staple of communities across the capital.

The oldest city in Western Europe, once the hub of a trading empire that connected Macau in the east to Rio de Janeiro in the west, Lisbon today feels staunchly Old World European, a sleepy town of nostalgic storefronts and scenic churches. But that’s only its façade.

In Rio, only specialty beer bars usually have a touch of sophistication, and generally, the beer there is much more expensive (mainly because of the high tariff on imported hops), the regulars are more demanding and the food is made by a “chef.” This in contrast to the humble botequim, the traditional family-run bars that serve simple snacks. But Hocus Pocus DNA strikes a balance between the two: it’s a brand-new bar with a botequim soul that slings craft beers and thoughtfully conceived appetizers to go with them. It’s also the name of an acclaimed artisanal brewery – one of the best local breweries in town, in fact, operating in Rio since 2014 – whose products are sold only in specialty stores and bars.
