If you were to ask me what my ideal lunch is, I would answer without hesitation: paccheri alla Genovese with a large piece of stewed veal shank for the first course, followed by a big ball of buffalo mozzarella (preferably from Tenuta Vannulo, an organic buffalo dairy in Capaccio) with eggplant parmigiana on the side. The backbone of this perfect meal is the Genovese, a simple yet miraculous sauce made of meat (veal, beef or pork) and a heap of onions (red or white). Even those who say they don’t like the taste of onions are forced to recant once they taste the Genovese (after hours spent simmering with the meat, the tenderized and translucent onion slivers have no trace of the astringent smell or bite of raw onions).

Years ago, when it was a booming industrial center, Poblenou saw thousands of workers stream in every day to toil away at one of several factories in the neighborhood. Hearty fare was required to keep them going – sure, taste mattered, but sustenance was the most pressing concern. Poblenou may no longer be filled with factories, but there are still plenty of people who spend their weekdays in the area, working at one of the many start-ups, tech companies or communications firms that have set up shop in their place. When it comes to lunch, these 21st-century workers want the same thing that those who came before them did: lunches that fill their stomachs and satisfy their taste buds without leaving a big hole in their pockets.

The entryway of Espai Mescladís is jam-packed with people: neighbors, workers and visitors who come and go all day long, and waiters walking from the kitchen to the tables on the terrace. But there are also dozens of people staring out from black and white photos that cover the restaurant’s walls; some are alone, others in couples, families or groups, smiling and laughing. All the people pictured at one point emigrated to Barcelona, and whether they’re still living in the city or have moved elsewhere, their stories are always present at Espai Mescladís. The photos, taken by the photographer Joan Tomás, were originally part of an exhibition organized by the Mescladís Foundation, a multifaceted initiative that provides tangible and sustainable economic programs, particularly in the form of job training, for migrants and refugees in the city.

In the Caucasus, guests are considered gifts from God. Georgians like to call them okros stumrebi – “golden guests” – an endearment that illustrates the stature the ever-hospitable Georgians give to those they host. And whenever our own golden guests come to visit in this remote corner of the world, we never fail to entertain them in our own surrogate dining room, Shavi Lomi (the Black Lion). The cellar restaurant is an homage to Georgia’s favorite artist, Niko Pirosmani, a naive painter whose favorite subjects were animals, a singer named Margarita and feast scenes. The flea-market furniture, tablecloths and china make the Black Lion an ideal setting for anybody hankering to create a one-of-a-kind, laid-back feast scene of his own, with hearty original takes on traditional Georgian cooking.

Bodega Bartolí opened in 1939 as a little bulk wine shop in Barcelona’s Sants neighborhood. Then everything changed for the bodega some 20 years later when a local client arrived with a stomachache. He asked a young Marina Dolz, who was minding the wine shop with her husband, if she could prepare some soup for him. It was the first dish she cooked there and, since then, Bodega Bartolí has moved far beyond simply being a wine store. At the time Bodega Bartolí opened, Sants was still an industrial quarter with several factories and thousands of workers. During the 1940s, the bodega sold both bulk wine to the neighbors and factory employees and barreja (a very traditional drink made of Muscat wine and anise liquor) to the wheelwrights passed by everyday.

In 2005, the city of Tbilisi bulldozed a riverside row of some the best restaurants in the capital to make way for a lackluster park and a gondola to take tourists to the ancient ruins of the Narikala Fortress, which overlooks the Old Town. City Hall justified this act of gastronomic destruction by stating the property had been illegally privatized under the previous administration, but everyone knew it was a land grab. And among the many restaurants it razed was Megrelebi Manoni, the best Megrelian restaurant in Tbilisi. Of all the regions that make up “Georgian cooking,” the western province of Samegrelo is the most distinctive.

Rod is at his seat at the end of the bar, his booming Scottish voice subdued by the spirited dim of a couple dozen Friday night regulars speaking mostly English in a variety of accents. We make our way to the steam table in the corner of the room to find it empty. Looks like there may have been chicken wings in there. If you want to munch free food at the weekly happy hour at Betsy’s Hotel bar, you have to get here at 6 p.m., when it starts.

This funky restaurant’s name was inspired by its address, on one of the main streets in the Athens district known as Neos Kosmos, or New World. It could just as well be called Terra Incognita, so distant is it from the usual areas frequented by locals and foreigners alike for entertainment and good food. And yet, geographically, it’s just a short walk from a new institution that has already claimed its rightful place among the “must sees” of the Big Olive: the National Museum of Contemporary Art.

La pizzaiola, played by Sophia Loren, peddles pizza from a counter on the doorstep of her street level apartment. She kneads dough while crying out for custom in a thick dialect and as clouds of flour fall to the cobbled Neapolitan street. This scene comes from one of the great cinematic homages to a city: Di Sica’s L’Oro di Napoli (“The Gold of Naples”), a 1954 a film that grapples with the bittersweet tastes of comedy, tragedy, hustling and the art of making do. There’s nowhere better to see Naples in all its “golden” glory than in the very neighborhood in which the film’s star, the inimitable Totó, grew up and where parts of the film are set: La Sanità.

There’s something special about Crete, Greece’s biggest island. The country’s most fertile region, it has a long history of food and wine production that stretches back to the Bronze Age, making Crete one of the most interesting culinary destinations in Europe. Bordered by the Aegean Sea to the north and the Libyan Sea to the south, the island is home to over 70 different edible herbs and wild greens, and local farmers produce a wide range of products, from Mediterranean staples like olives, tomatoes and eggplants to more tropical produce, such as mangoes and papayas.

Sants is a working neighborhood with an industrial past and a communal present, both of which it proudly flaunts. There are the street names – like L’Espanya Industrial, Carrer Wat (dedicated to the engineer James Watt) and Vapor Vell (Old Steam) – that tell the story of industrialization in Catalonia, and the two buzzing municipal markets and the many bodegas and restaurants, like Terra de Escudella or Bodega Salvat, that serve as meeting points for an engaged community. Although shaped by a diverse set of international influences, the neighborhood’s sophisticated culinary scene is tied together by something more local: vermut culture.

When we first discovered this delightful ouzeri in Neo Psychiko last May, we were thrilled to have found a place that specialized in Politiki Kouzina – not the cooking up of politics but the cuisine of Constantinople, often called simply I Poli, or The City, by Greeks even today. Ironically, mutual friends had chosen it to fete a Turkish guest, a visitor from Istanbul, which seemed a culinary version of taking coals to Newcastle. But she pronounced the fare delicious, and smacked her lips over such shared dishes as Imam Baildi, dolmades and bourekakia made with phyllo.

For 2,000 years, people have flocked to the Abanotubani baths, whose hot sulfuric waters have long been fabled to possess magical healing qualities. The Persian king Agha Mohammad Khan soaked there in 1795, hoping to reverse the effects of the castration he suffered as a child. He dried off, found his conditioned unchanged and razed Tbilisi to the ground. While people continue to espouse the curative properties of the sulfur baths, we can only vouch for their powers to relieve stress, loosen up sore muscles and help poach the hangover out of you. It is the latter attribute that inspired the local chef Tekuna Gachechiladze to open a restaurant last year that might not cure erectile disorders, but is definitely designed to nurture alcohol-stricken bodies back to life.

Have you ever met a restaurant owner who has been a house painter, real estate agent, rug dealer, bread deliverer, camel trainer and interpreter as well as running a tourism business? Meet Ahmad Alssaleh from Palmyra, Syria. Although he is only 31 and the youngest of ten children, he is not only unstoppable, he is about to celebrate the first anniversary of one of the most imaginative and best restaurants we have ever been to anywhere – not just Athens. But we’ll get to the food later. His story will whet your appetite, as it did ours. It all started back in 2009 when Alssaleh met Magda, a Greek girl who’d gone to Syria as a tourist.

Pizza, as you might already know, was born in Naples. What you might not know is that in Naples, fried pizza existed before baked pizza. And although Neapolitans have raised pizzamaking in the oven to an art form, their skill at turning out fried pizza is even greater. As with so many local specialties in this city, it’s hard to say who makes the best fried pizza here; there are improvised pizzerias in every corner of Naples, street vendors that make a really good pie. There’s a saying here, voce e’ popolo, voce e’ dio (the Neapolitan version of vox populi vox dei), which means that something is certain – there’s no doubt. And that applies to Masardona's pizza being one of the best in the city.
