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.

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.

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.

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.

Dozens of urban legends swirl around the city of Naples – strange stories repeated a thousand times that, somewhere along the line, become credible. One of those urban legends concerns biscotti all’amarena, or black cherry cookies: people often say that they are made from day-old cakes. To create this typical Neapolitan sweet, bakers chop up pan di spagna (sponge cake) – the bit that is supposedly reused – and then mix it with black cherry syrup, cocoa and cinnamon. The mixture is then covered with a short-crust pastry shell and baked as a loaf, after which they’re cut into small rectangles.

When I was a little girl, a Popsicle was a big deal. Summertime meant that the ice cream truck, bell tinkling, would trundle through the neighborhood where I lived. After a frantic plea to Mom for money, she counted out coins and I raced to the corner where the rest of the kids were already gathered, waiting for the vendor to dig through his icy case for cherry, lime, orange, or the reviled banana. The odor of amyl acetate (the chemical used for artificial banana flavoring) remains cloyingly in my memory. Remember? Hot summer days made those frozen snacks melt quickly, down childish fingers and the side of the hand, down the wrist and almost to the elbow in sticky trails of blood red and pale green. Nips of the cold treat slid in a chilly track from tongue to stomach, giving a few moments relief from childhood summers’ heat and humidity.

The song “My Way” may be a staple of every karaoke bar in Japan but it’s also a fitting description for the Japanese fast food staple of “curry rice” as served at both Rojiura Samurai Curry and CoCo Ichibanya. One can find four Tokyo outposts of Rojiura Samurai Curry, a Hokkaido curry maker from Sapporo, in Hachioji, Shimokitazawa, Kakurazaka and our favorite, Kichijoji. It seems these Japanese curry masters are fond of opening shops in cool neighborhoods where the locals will appreciate the uniqueness of this favored Japanese dish. Much like ramen noodles, curry rice is adapted from a foreign cuisine as a form of fast food in Japan.

Kapnikarea, a tiny music café-restaurant, takes its name from the Byzantine church nearby in the middle of Ermou Street. The street, dedicated to Hermes – a god of many attributes, including trade, thievery and smooth talking – and thronged with tourists and shoppers day and night, is an unlikely location for this unusual eatery. You might expect it in neighborhoods like Psyrri or Exarchia, where the eccentric is commonplace, but not opposite H&M and in the same zone as Zara and Marks & Spencer. In all fairness, Kapnikarea was there first. And when it opened in 1977, it was an avant-garde sandwich shop, a pioneer in the land of souvlaki and spanakopita. This version of fast food barely existed back then although it caught on fast. Nineteen years later, Dimitris Sofos took over the shop from his father and completely transformed it.

“Mamma mia!” exclaims our Californian friend, as he tastes a slice of cod carpaccio for the first time. Better yet, let’s call this dish, made by one of the oldest fish shops in Naples, Norwegian stockfish sashimi. We are in Porta Capuana, and Vincenzo Apicella is carefully slicing dried fish (stockfish is an unsalted fish preserved only by cold air and wind) that has been rehydrated. He seasons the very thin fillets simply, with the juice of a fragrant Sorrento lemon, and serves them together with Sicilian green olives. The dish is proof, if it was needed, that good food tastes best when it is prepared as simply as possible.

For thousands of years, snails have been an easy source of protein, particularly during lean times. But for the Romans, these slimy mollusks were more than just a back up – a meal of snails was considered an exquisite feast. The Romans were experts on the subject. They studied and classified snails; they knew where to find the edible species in the south of France, Greece, Italy and Spain, how to farm them, how to clean and prepare them and, of course, how to cook them. Records show that the snails were roasted with different seasonings, like garum, pepper or olive oil, or cooked in wine.

Considering how much hype has been laden upon it since 2016, when a few galleries moved into some of its former warehouses, you’d think the light-industrial, heavily residential neighborhood of Marvila would already be out of fashion. Yet, step outside the cluster of streets hosting these art spaces, co-working hubs, brewer-bars and the famed cultural center Fabrica Braço de Prata, and Marvila as a whole still feels a long way from being the next big thing. Located between Lisbon’s airport and the river Tejo, this sprawling eastern district is mostly unchanged when you move away from the marginal and towards its heart: the expansive Parque Bela Vista.

Walking through Tokyo’s Shin-Okubo neighborhood – AKA Koreatown – can be sensory overload. It’s Saturday night, and we weave through throngs of people along Okubo Street, passing crowded cafes and Korean cosmetics shops. The soundtrack of Korean pop music drifting from every restaurant and café is punctuated by shouts from inside a Korean grocery or the blare of a pachinko parlor. Every shop is painted in an audacious purple or pink or else a dazzling orange or yellow, competing for attention. Scents of foods spicy and sweet drift from storefronts. Tokyoites come to Koreatown for two reasons: shopping and food, but we haven’t come to shop. The crowds thin out along Shin-Okubo’s backstreets, though the shops and restaurants are just as packed.
