The peripheral neighborhoods of Barcelona – untouched by tourism and with cheaper rents – are a land of opportunity for chefs seeking an affordable place to set up shop. These areas in turn attract gourmet gold seekers in pursuit of a brilliant meal at a friendly price. In the residential streets of Sants, not too far from the city’s main train station, one restaurant shines particularly bright, with its eclectic style, influences and, of course, flavors: MinE. MinE is a combination of combinations, beginning with the owner and head chef, Martin Parodi. Born in Buenos Aires, Parodi is the son of a Japanese father and an Italian mother. He grew up in Barcelona, studied in France and then worked in a number of European countries.

Mexican diners offer a place for many in the capital to go for simple eats, often for people struggling to make ends meet. The key is to look for a crowded lunch bar lined with clients downing food before they have to head back to work. For example, if you find yourself strolling down 5 de Febrero, a few blocks south of the Zócalo, about to hit the new, city-funded arts district along Regina and San Jerónimo, consider Panadería La Joya. One of the classic greasy spoons downtown, La Joya stands out not for its innovation or hip atmosphere, but for its spot-on, tried-and-true renditions of Mexico’s hits. The place feels timeless. We tracked down the oldest worker, there for 40 years, and he admitted he had no idea when or who began the place.

Horchata, a unique and deliciously refreshing concoction made from chufas (tigernuts), water and sugar and served chilled, is beloved across Spain. In Barcelona, there’s really only one place to try the stuff: Horchatería Sirvent. The faithful line up here in droves during the summer months, waiting with ticket in hand to sip the best horchata in town.

The sleepy residential neighborhood of Melissia, which lies northeast of downtown Athens and under Mount Pentelikon, is a rather unlikely place to visit. The suburb doesn’t have any notable sites, and apart from Kozi’s, a lovely South African meat restaurant, there’s not much in the way of distinguished restaurants. So in 2012, when Ornel ‘Oli’ Mingo opened Psarokokkalo in the suburb, everyone though he was crazy. “People told me that there’s no way clients will come here to eat. But I saw potential. The rent was relatively cheap and there was some space for tables outside,” he explains. Fast-forward six years and Psarokokkalo (which means “fish bone” in Greek) has tripled in size, taking over the adjacent shop, and is now a beloved seafood taverna that attracts customers from all over Athens.

Way before brunches, special bowls, latte foam art and white marble counters took the city by storm, restaurants like Petite Folie, Lorde, Saraiva’s, Bacchus and Belcanto were the coolest cats in Lisbon. You wouldn’t walk in not wearing a nice jacket or a dress. You would never go straight to your table – first, you would sit at the bar, greet your favorite waiter, who knew you by name, and order your usual drink, which he would already be preparing. But those days are gone, like most of those restaurants – the ones that aren’t, such as Michelin-starred Belcanto or the newly reopened Saraiva’s, have changed dramatically.

In 2001, we rented a room in Vera, near the Philharmonia, and the first thing we did after dumping our bags on the bed was find some coffee for the morning. The best we could score from the little neighborhood market was a can of Pele, a fine-ground instant coffee powder that seemed less toxic than Nescafé, which was also much more expensive. There were no coffeehouses in Tbilisi back then. Pretty much the only place you could find an espresso was at the Marriott and Prospero’s, an English language bookshop and expat hangout. Otherwise, there were little joints with “café” signs serving khachapuri and Turkish-style coffee brewed in little plastic electric kettles – providing there was electricity. That was Tbilisi’s coffee culture.

Nestled in a small cove that hides it from the nearby center of Sarıyer, not far from where the Bosphorus meets the Black Sea, Rumeli Kavağı is officially part of Istanbul yet has managed to keep the structure, atmosphere and relative isolation of a real village. The only apparent sign of the surrounding megalopolis is the sight of the massive Yavuz Selim Sultan Köprüsü, the third bridge to span the Bosphorus, opened in 2016. Over a quarter of the neighborhood’s almost 4,000 inhabitants are involved in the fishing business, an integral industry in a city that partly owes its worldwide fame to a long-standing meyhane culture. Dining on grilled fresh fish and sipping on a glass of cloudy rakı, particularly while watching the lights of the city dance on the Bosphorus, is one of Istanbul’s purest pleasures.

The humble pie is perhaps one of the world’s oldest street foods. A quick survey of global food history finds pies everywhere, from East to West, mirroring the local ingredients, agricultural practices and dietary needs of different cultures. In Greece, pies certainly go way back. There are a few references to pie-making during the Minoan times (2600-1600 BC), but most mentions are from around the 5th century BC onwards, when pies were generally known as plakous. Ancient Athens was particularly famous for its bakeries and pies, especially a cheese pie known as tyronos plakous or tyron artos. They were the main snack consumed by Athenians while listening to public speeches at the Agora or while watching theater.

Twenty years ago, Rio de Janeiro was teeming with food markets: big indoor venues full of stalls where people could go to buy groceries, fresh meat and produce, but also stay for a while to have a drink or two, maybe some appetizers, or even sit down for a meal. As time went by cariocas spent less time in these markets, instead shopping in grocery stores and eating at restaurants; the markets continued to limp forward only because of some strong-willed and stubborn merchants who refused to shut down their businesses.

Our eyes take a moment to adjust to the dim light upon walking into Ladrio. The room is like a vault, its brick walls and floor emitting a scent familiar to anyone who’s ever been in a cave or stone cellar. This mustiness is comforting, however, and the cool air a welcome reprieve from the furnace of the Tokyo summer outside. Soon we can make out several low tables extending back into the narrow space. People sit alone or in pairs sipping coffee or puffing cigarettes. Some converse in hushed tones as Edith Piaf is piped quietly from an unseen stereo. A few heads swivel in our direction but gazes never linger here.

While on our Downtown Athens walk, we spied a grill master preparing his souvlaki on a hot griddle rather than on the customary charcoal fire – as we learned, this style of cooking has enraged many a purist over the years. Yet the result is still juicy and exceptionally filling, so we’re not complaining.

All morning, as we zoomed down south from Naples on a motorcycle, inky clouds threatened rain. So when we arrive at Rivabianca, a mozzarella di bufala cooperative in the village of Paestum, with our clothes still dry, we exhale deeply, not realizing that we had been holding our breath. Inside the dairy’s production center, separated from the small shop by large windows and a big metal door, it looks as if the rain has already come and gone – the tile floor is covered in water. “Wait just a sec, you’ll need these to go inside,” says Rosa Maria Wedig, the owner of Rivabianca, handing us two plastic bags. Before we can make a move, she’s bending down and shoving them on our feet, using duct tape to secure them around our ankles.

New York’s street food vendors usually ply their trade where potential customers congregate. On side streets in midtown Manhattan, they set up four and five abreast for the weekday lunch rush. During warm-weather weekends, they feed footballers and their fans outside ball fields in the Brooklyn neighborhoods of Red Hook and East New York. In Queens, they do business beside a miles-long stretch of Roosevelt Avenue where it passes through Woodside, Jackson Heights, Elmhurst, and Corona; they cluster thickly near station stops of the elevated 7 train. The setting of the D’Angelos Italian Sausage truck presents a dramatic contrast. Monday through Saturday, the truck parks in a long-established spot on Woodhaven Boulevard, on the border between two largely residential neighborhoods, Middle Village and Rego Park, beside the green expanse of St. John Cemetery.

Matosinhos, a small city just north of Porto, is used to change. It has an industrial air to it, due to its 19th-century harbor, and its past prosperity was connected to the fish-canning sector, which peaked during World War II and declined from the beginning of the 70s. The numerous abandoned warehouses attracted nightlife during the 1990s, with clubs finding a fertile zone for noise. The completion of the long-delayed tidal pool, built by Portugal's starchitect, Alvaro Siza (who was born in the city), put it firmly on the map again after the project was delayed for decades. In January, the launch of the new, spiralling cruise ship terminal added to the contemporary design-y feel that has been developing on its otherwise rugged coastline.

A few intrepid trajinera (gondola) operators sit along the Cuemanco Dock, waiting for tourists to take through the canals. We’re in Xochimilco, the southern-most borough of Mexico City. It’s a popular weekend destination for trajinera rides, when entire extended families float along the canals, drinking micheladas (beer cocktails) and eating elotes (grilled whole corn cobs) sold off canoes. But this weekday morning is quiet. As the morning fog burns off, we set out on a green, motorized trajinera into Xochimilco’s Natural Protected Area. Before it was a preferred weekend getaway for chilangos, Xochimilco was the agricultural heart of the Aztec capital Tenochtitlan. Our destination is a chinampa, a man-made agricultural plot that “floats” on the city’s shallow lakebeds.
