We usually steer clear of the touristy Old City district of Kumkapı, where you are more likely to be accosted by an aggressive maitre d’ trying to corral you into his overpriced fish restaurant than to find something simple, tasty and reasonably priced to eat. Sadly, in order to beat the competition next door, most of Kumkapı’s famed fish restaurants seem to have invested more in aggressive customer corralling tactics than in kitchen talent. However, tucked into the neighborhood’s backstreets, we’ve found a few hidden dining gems that locals in the know frequent. When in the area, we skip Kumkapı’s fish restaurant strip and make a beeline for Doyuran Lokantası, a serious little eating sanctuary on a nearby side street.

A legendary snack bar sits on a corner of Praça Luís de Camões, a busy square dedicated to one of Portugal’s most celebrated poets (his most famous work is the epic Os Lusíadas, a fantastical interpretation of the Portuguese voyages of discovery, narrated in Homeric style). The square is a major thoroughfare in Chiado and witnesses thousands of journeys daily. Many passing through make a pit stop at O Trevo. This tiny and perpetually packed eatery has historical roots in the area; traces of the old sign, “Leitaria Trevo,” over the marble entrance reveal its beginnings as a dairy some 80 years ago.

Watching old Greek movies from the 1950s, '60s and '70s has been a rite of passage for every single generation raised in Greece from the '80s onwards. When we were young, these movies played endlessly on TV, getting us acquainted with the Greece our parents grew up in.There were a number of things that both puzzled and delighted us – chief among them, the patisserie-as-meeting-place. The heroine, wearing a pillbox hat over expertly coiffed hair, would meet her girlfriends or potential love interest in grand-looking pastry shops, where she would be served by waiters in uniforms and eat a pasta, an individual portion of dessert: soft sponge cake with almond and cream or chocolate fillings.

Dear Culinary Backstreets, I keep hearing buzz about “yangmei” season in Shanghai. What’s all the fuss about this fruit? What’s in a name? Shakespeare could just as easily have written, “A yángméi (杨梅) by any other name would taste as sweet.” This little red Asian fruit has a plethora of monikers: Myrica rubra, Chinese bayberry, yamamomo, Japanese bayberry, red bayberry and waxberry. But a decade ago, the sweet and sour fruit was rebranded as the yumberry in the United States (where it is sold in juice and powder form, but not fresh, due to an import ban on the live fruit) to stand out from other exotic “superfoods.”

June is probably Lisbon’s most euphoric month, due to the city’s biggest street party that celebrates the patron Saint Anthony. Though the festival officially takes place on June 12-13, the party runs all month long, especially in Alfama, Mouraria and Graça. The smoke of sardines grilling, colorful decorations, makeshift neon fairgrounds and pimba music blaring from outdoor speakers enliven the narrow roads of these traditional neighborhoods. The bedlam isn’t for everyone, however, and for those who want to find a quieter spot that still celebrates fresh, seasonal fish, Largo de Alcântara is a good alternative. Located in the western part of the city, between Santos and Belém, this zone is a concentration of cervejarias and marisqueiras.

Rubi wanted two things for his 13th birthday: a bicycle, and to see his dad, Ahmed, again. It was the end of November, and it had been three months since his family was whole, since Ahmed left for Germany with Rashed and other colleagues from Salloura. Rubi’s days in Istanbul were a steady grind, all blending together in a dim purgatory: wake up at 6 in the morning, get to work at the shirt factory two bus rides away by 7, iron, sew, take the boss’s orders, go home 12 hours later, eat, sleep, repeat. Before Ahmed left, he had been working at the Salloura factory, learning his father’s trade.

Rashed wandered aimlessly in the dark, autumn leaves and twigs crunching under him with each step. Apart from the light from his Samsung, the scene around him was pitch black. “I just need to get signal so they can send me a recording of Lulu’s voice,” he said, hopeful but frustrated. Lulu is his beloved two-year old niece – the one who almost convinced him to stay in Istanbul when he squeezed her goodbye. It was the last time they touched before he left his family behind to embark on the harrowing three-week journey to Germany.

Tucked away in an alley in Istanbul’s Aksaray neighborhood, Şirket Alahdab is a small grocery store overflowing with Syrian staples: pickled baby eggplants, dried leafy greens, cans of clotted cream for desserts. When we enter the store, Istanbul temporarily fades away and Damascus or Aleppo take its place. “All real,” the clerk declares proudly, as he shows off his goods. “Smuggled from Syria.”

“No hamsi, no money.” Mert Kanal hoses down empty Styrofoam containers and surveys the leftover catch in his market in Sinop, on Turkey’s Black Sea coast. The gulls squawk, fighting over scraps on the dock while fishermen tidy their nets for another night of fishing. The hamsi, or anchovies, are gone for the season, moving up the coast in dwindling numbers as hulking factory ships chase them. While mackerel, turbot and whiting are all fair game for fishmongers, hamsi holds a special place in Turkish cuisine. Unlike the slimy, salty canned form of the fish reserved for eccentric pizza toppings in North America, anchovies are eaten fresh in Turkey. Lightly battered, quickly fried and served with a slice of lemon, hamsi are gobbled down by the kilo, bones and all.

Settled by Greek refugees from Turkey after 1923, Nea Erythraia is a northern suburb of Athens that started off very low-key and has now evolved into a buzzing shopping and nightlife area, full of cafés, bars, restaurants and gelaterias. Despite the recent boom, many places that have been local favorites for over a decade now are still popular. One such venue, a small, unassuming restaurant with the welcoming name of “Kali Parea” (meaning “good company” in English), is hidden in a quiet street off the main road. Its faithful clientele come here to savor seasonal fish (mainly small fry) and seafood (calamari, octopus and shrimp), prepared either fried or grilled.

The rustic family favorite Can Pineda has been holding down this corner of Barcelona’s El Clot neighborhood since 1904. It was not a restaurant originally, but a typical wine shop and canteen, where plenty of life could be found amongst the wooden barrels that now slumber peacefully on their perch up above the dining room. At that time, the place was frequented by local factory workers, who would come for a glass of wine to go with a simple meal or to drink while warming up their lunch boxes. The then-owners would put a pine branch on the door to signal the arrival of the vi novell, or new wine of the year, and from the pine, pi in Catalan, came the name Can Pineda, which translates roughly to “The Pine House.” Today, El Clot is part of the new high-tech 22@ district, which is focused on innovation and research but maintains in its oldest streets the spirit of the village (Sant Martí de Provençals) that once flourished here, with its own market (dating back to 1889) and walls that remain from Barcelona’s first Industrial Age. Can Pineda sits right in the middle, a small but welcoming eatery with just 30 seats, decorated with the characteristic blue azulejos tiles, those wooden barrels and a few excellent hams hanging behind the bar.

When we picked up a cab from Meşhur Unkapanı İMÇ Pilavcısı recently, it turned out the driver had just been there for a refuel himself. Sensing a captive yet interested audience, he held forth all the way to Beyoğlu about where to eat well and cheaply – without stomachaches ensuing – in Istanbul. We’re always happy to discuss the finer points of kuru fasulye (stewed beans), but this driver seemed to have a particularly deep interest in the subject. After debating the merits of various canned brands (“Yurt” brand or nothing, in case you were interested), he dived into the subject of soup.

Editor's note: The chef and owners of Mekan have moved on to a new location, which they've named Mari. We're sorry to report that Mekan itself has since gone downhill. In the great multicultural Anatolian kitchen, questions about the ethnic or national origins of foods are often cause for forks and knives to fly. A porridge called keşkek is a hot-button diplomatic issue between Turkey and Armenia, and we won’t even get started on the ongoing baklava debate. So what to make of this cuisine that draws influences from every corner of the former Ottoman lands, a territory stretching from the Balkans to North Africa? The answer might be in a simple term that’s becoming popular among Turkey’s minorities. The word Türkiyeli means “of Turkey” and differs significantly (and quite intentionally) from the word Türk, which often adds ethno-religious shades to nationality.
