QUICK BITE: Spend the day eating your way through Sants, a lesser-explored neighborhood with a booming local food scene and an interesting history. We’ll dig into markets and old vermuteria, pastry shops and down home restaurants, but we’ll also find the pulse of Sants in some contemporary culinary projects.

Our “Culinary Secrets of the Old City” walk goes beyond the major monuments and into the backstreets where all of the serious eating is done. We’ll set off through the atmospheric, lesser-explored market streets around the Egyptian Spice Market and then go deeper into the untouristed Fatih neighborhood.

Lisbon seems to be getting its groove back. Or at least, more people are taking notice of this city’s unique character and clearly taking to it. Recently, Vogue and The New York Times profiled the Intendente district, an up-and-coming neighborhood in the city center; Monocle magazine held its first “Quality of Life” conference in Lisbon; and many friends of ours, from Istanbul to San Francisco, are sharing beautiful photos of their latest trip to the city. Oddly, in a city on the upswing with such a rich culinary heritage, we found there was little storytelling on the subject of food and how it impacts Lisbon’s urban culture, be it in print, on the Web or on the ground (as in a tour or other guided experience).

If Istanbul is Turkey’s New York then Izmir is definitely its New Orleans. In this sun-kissed Aegean port city, peoples have come and gone for millennia – Greeks, Cretan Turks, Sephardic Jews, Armenians, Levantine Europeans and Kurds, to name a few – each contributing to the culture of the place, but also, we sense, surrendering to a lifestyle distinctive to the city. To be from Izmir is to know good food and take the time to enjoy it. Exploring the markets, bakeries, lokantas (homestyle restaurants) and tea gardens of the narrow streets that spread out below the ancient Roman-built agora, we are always struck by how local – so “Izmirli,” as the Turks say – the cuisine here is. Digging a little deeper, a wide range of Mediterranean influences reveal themselves in this city’s kitchen, reflective of its rich history.

Metin Akdemir is a filmmaker based in Istanbul. In 2011 he made a short film about street vendors in the city. The film, “Ben Geldim Gidiyorum” (“I’ve Come and I’m Gone”), won several awards in Turkish and international film festivals, and we think it’s a very valuable piece of work that captures a side of Istanbul’s culture that is slowly disappearing.

You get to Bar do Alto by taking a zippy mototaxi up the snaking streets of the Babilônia favela and then walking 10 minutes up jagged staircases that eventually bear right. On the route, you’ll pass by slices of life that make favelas a museum of Rio, where the city’s symbols and icons are on display in the bare and human way that’s made possible by close quarters of self-made dwellings. There are the evangelicals raising their voices in weeknight prayers. Shirtless men with leathered skin that speaks to long day jobs, now tipping back tall evening bottles of beer. Children playing soccer as overheated cops in bulletproof vests slump on nearby benches.

My wife, Kurdish in-laws and I are enjoying an early meal at Gabo, one of Diyarbakır’s most successful new restaurants. It gets dark early this time of year in the city, and the dry air carries the ayaz chill, which engenders a need for a hearty soup and hot tea. The owner, Cahit Şahin, shares stories of the place’s beginnings. “When we applied for a restaurant license, City Hall just laughed,” he tells us. “‘For a vegetarian place?’ they said, ‘In Diyarbakır? Go ahead! It doesn’t matter if we grant you one or not. You’ll go under in three months!’” But that was nine months ago. Gabo, which bills itself as the predominantly Kurdish southeast region’s only vegetarian restaurant, is thriving. In fact, they are doing so well that Şahin and his fellow owners are planning to open franchises in the western Turkish city of Tekirdağ and in Istanbul. As Şahin talks, he gestures at the bustling café around him. “We used to work as tutors for students preparing for their standardized exams. We were just sick of the rat race, of always being tired and worn out. I envisioned a cozy alternative joint where I could drink tea, listen to jazz and play backgammon with my friends.” He laughs. “We haven’t touched a backgammon board since we opened the doors!”

Editor’s note: Tbilisi was a new addition to Culinary Backstreets this year, and as we look back on all the great eating we did in 2015, we can’t help but notice that so much of it took place in the city's Sololaki area. There’s a typecast in Georgia that when somebody wants to go into business, they open up a khinkali restaurant. There is a logic to that. About a million people live in Tbilisi, a city built impetuously along the hilly banks of the Mtkvari River. And the adoration every single one of these people has for this boiled dumpling is so reverent, it is as if they see Jesus and his disciples feasting on a steaming platter of kalakuri khinkali for the Last Supper as they bite a hole into the dumpling and slurp its tasty broth.

Editor’s note: To give 2015 a proper send-off, we’re taking a look back at all our favorite eating experiences this year. Hamo’nun Yeri The nohut dürüm, a simple wrap of mashed chickpeas, peppers, parsley and spices, may be a popular breakfast choice in certain districts of the southeastern province of Gaziantep, but we'll eat it anytime and are prepared to travel far and wide to do so, as this treat is by no means common in Istanbul. Hamo'nun Yeri is located in Güngören, a densely packed working-class district located well outside the radar of tourists and more affluent Istanbulites. Made with bread hot out of the oven from the family's bakery down the block, the dürüm – and a chat with the friendly Gül brothers – is more than worth the trip.

Editor’s note: As the year comes to a close, we honor some of the people who are keeping up traditions on the Japanese food scene. And we remember the foods we’ve dreamt about eating again and again from each of them. Nodaiwa This 200-year-old restaurant, one of Tokyo’s best sources of wild-caught unagi (freshwater eel), is housed in a building brought from Hida-Takayama in Gifu prefecture, which is famous for gassho-zukuri farmhouse architecture, with its massive dark wooden beams and thatched roofs. The structure was dismantled and then hauled down to Tokyo piece by piece and reassembled in the modern building where Nodaiwa offers a small glimpse of traditional taste and skill, with vintage touches throughout. Fifth-generation chef Kanejiro Kanemoto keeps the tradition alive and deserves his Michelin star. His passion for offering only the best eels available is evident in everything he serves.

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.

National Route 246 is one of Japan’s main byways, stretching for over 76 miles and snaking through the center of Tokyo. The small part of Route 246 that runs between Shibuya and the Meijii Jingu Shrine was recently recreated for one of the best-selling video games of all time, Gran Turismo 3: A-Spec. It also happens to be the location for the food court heaven known as Commune 246.

Büyükada has long been a popular destination for İstanbullus seeking a break from harried metropolitan life. With its array of quaint köşkler (Ottoman-era wooden mansions), walkable woods and relative quiet (automobiles are prohibited, so there’s none of the modern world’s ubiquitous, underlying machine hum), this five-square-kilometer island, about an hour’s ferry ride southeast of the city center, serves as a welcome counterpoint to the bustle and bother of existence in an urban agglomeration of 14 million. There’s just one problem: The dining scene is insipid. There’s no shortage of fish restaurants along the esplanade, just east of the ferry terminal, but in our experience they’re undistinguished – indeed, indistinguishable – and maddeningly overpriced: in short, tourist traps. Some of the boutique hotels offer reasonable, if unexciting, fare on-site, but if you want to dine out, that row of uninspired seaside eateries is the only game in town.

In May, we visited some friends on the beautiful island of Amorgos. While we were driving to the south of the island, in the Kolofana area we came across a very small kafeneio, or traditional coffeehouse. We only wanted to make a quick stop for a cup of coffee and a glass of water, but we ended up getting a lot more than we bargained for.

Kim Díaz, a well-known local restaurateur and owner of Bar Mut tapas bar and El Mutis cocktail bar, wanted to pay tribute to one of the most humble and sadly underrated Spanish snacks, the sandwich. Sandwiches are generally made by most Barcelonan bars with defrosted cheap bread and greasy fillings, and good ones are not easy to find in the city (though we have written about some great ones). Entrepanes Díaz opened last February with the goal of giving the sandwich the respect it deserves.
