One feels cooler simply for patronizing La Secina. The architecture of the restaurant seems to evoke a perpetual party vibe. At dinner, individual lights dangle on long lines amid a mesh of vines that gives the cavernous space a homey, DIY feel. The teal and orange on the wall are bright and clean. The stenciled restaurant logo and exhortations of “bienvenidos” feel as organic as they do well designed. Downstairs, picnic tables radiate outwards from a long, inviting bar. Upstairs a dedicated booze closet services a patio that looks out upon a beautiful church across the street. And on weekends, live blues bands play everything from Albert Collins to Muddy Waters to Robert Johnson.

Convincing someone to accompany you to Istanbul’s Pendik district is no small feat. The Asian-side suburb is located in the far eastern reaches of the city, a trip of at least an hour and a half from the city center requiring no less than three metros and a cab. We've been met with moans and groans upon mentioning the name, as the district is synonymous to many with the wildfire-like urban sprawl that has engulfed Istanbul over the years. Those up for the journey, however, are rewarded handsomely at Lipa, a meyhane serving Bosnian specialties. The neighborhood of Sapan Bağları is home to a large population of natives from Sandzak, a predominantly Bosnian Muslim region now split across modern-day Serbia and Montenegro.

In the southwestern part of Catalonia, in the province of Lleida, lies Les Garrigues, where the gray-green foliage of compact Arbequina olive trees stretches across some 20,000 hectares of the soft, dry landscape. This is where one of Spain’s best extra-virgin olive oils is produced. The olive tree has been cultivated in Catalonia since at least ancient Roman times, although it was probably first introduced by the Greeks in 600 BCE. Its cultivation developed alongside other typical crops that flourish in a dry climate – such as almonds, grains and grapes – until growing olives and producing olive oil became the main industry of Les Garrigues in the 19th century.

Like many of Mexico’s best taquerías, Tacos Manolo greets its patrons from a block away with its alluring smell. But it isn’t the well-known odor of fired achiote on a swirling spit of al pastor or the equally recognizable heavy scent of bistek searing on a griddle. No, the aroma wafting down this particular block of Calle Luz Saviñon is a mystery to the uninitiated – a unique, unplaceable perfume that allures as much as it confuses. It is the smell of onions and unknown meats and mystery sauces bubbling together, fusing into something greater and more delicious than the sum of its parts. It is the smell of the eponymous Taco Manolo, a one-of-a-kind dish that has brought the restaurant fame and accolades.

Between two simple slices of bread exists a mind-boggling array of possibilities – something not lost on Spaniards, who have turned sandwich making into something of an art form. In Spain, sandwiches go by different names depending on the kind of bread used and local custom. The type that’s generally called a bocadillo in Spanish and entrepà in Catalan traditionally comes on pan de barra, itself a broad category of bread, with varying dimensions, qualities and more specific names, including baguette, maybe chapata (ciabatta), depending on how round the bakery makes it, pistola (pistol) in Madrid and flautas (flutes) in Barcelona if it’s short and very thin.

Visitors to Istanbul's iconic Spice Bazaar encounter a place packed wall-to-wall with overzealous shopkeepers selling everything from saffron to sumac assembled in rows of majestic pyramids at slightly inflated prices. But for our money, the only spices worth a damn are found just outside in a humbler setting. Crammed behind a tiny kiosk perched in front of a fast-food restaurant that flanks one of the bazaar's entrances is the endearing Orhan usta. The loveable 65-year-old is a veritable master of çig köfte and a connoisseur of the spicy red pepper flakes cultivated in his hometown of Gaziantep, the southeastern city considered by many to be Turkey's culinary capital.

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.

What's better than a day at the beach? How about a day at the beach followed by fresh seafood and a cold beer in a vibrant neighborhood with views to boot? Bar do David sits on a busy corner in Rio's Chapéu Mangueira, a favela that overlooks the beaches of Leme and Copacabana. On a recent Sunday afternoon, the bar's two floors and outdoor area were packed with locals and tourists noshing on plates ranging from feijoada de mariscos, a white-bean and seafood take on the classic Brazilian bean stew, to the Estrela do David (Star of David), pineapple-mint pork rib tacos.

The oldest city in Western Europe, once the hub of a trading empire that connected Macau in the east to Rio de Janeiro in the west, Lisbon today feels staunchly Old World European, a sleepy town of nostalgic storefronts and scenic churches. But that’s only its façade.

Beyond the bustling districts of the centro, Lisbon’s port and the old neighborhoods clustered around it have always had a close connection with the waterfront and its industries, especially fishing. The city’s iconic varinas, itinerant fish vendors, lived and worked on the streets here until quite recently, selling their goods from a basket hoisted on their heads.

Tacos Beto is not a pretty place. Stacks of soda bottles, enough for weeks to come, serve as a wall that shields customers from the wind blowing down Avenida Dr. José María Vertiz. The plastic tables and plastic stools that surround the bottles seem older than the invention of plastic. A long, dusty awning hanging above the sidewalk seating advertises a brand of soda that Tacos Beto no longer carries, maybe never carried. The only visible beauty encountered at the restaurant sits on the arched wall above the steel fryer, or comal bola – orange and blue paint spell out the words “Tacos Beto – los de cochinada” (“Tacos Beto – the garbage ones”).

Spain, Italy, Greece, Turkey, Portugal, Morocco, Tunisia – one thing that unites this swathe of the Mediterranean is olive oil, whose use in the Fertile Crescent can be traced back to 6000 B.C.E. Olives arrived in the southern part of the Iberian Peninsula around 9th century B.C.E. with the Phoenicians. Ancient Rome saw huge quantities of olive oil from Hispania Baetica (currently Andalucía) being transported throughout the Roman Empire in millions of amphorae (made in Baetica). Spain leads production of olive oil to this day, with 45 percent of the global total. The majority (65 percent) of Spanish olive oil production is sold to Italy, where this oil is mixed with others (normally of the same quality, but not always) and sold under an Italian label.

Barcelona’s food shops and colmados offer culinary treasures all year long, but the holidays are a particularly exciting time for browsing their wares. The festive window displays show magnificent gift baskets overflowing with tasty treats – with many Spanish and Catalan specialties among them. Perhaps the most desirable items in holiday gift baskets here are the seasonal sweets, which previous generations would amass in quantities that would serve as “emergency” treats for unexpected guests the rest of the new year. (Thankfully, one can now find these year-round, so there’s no need to hoard them.) We’ve written previously about artisanal turrón, which continues to be handmade by a few family-run companies.

Though ceramic dishes or tinned sardines are the standard take-home souvenirs for visitors to Lisbon, a less traditional – but still unique – gift from the city is the source of the warming aroma that permeates its cafés morning, noon and night. A strong bica (espresso) is an integral part of Lisbon’s smellscape, and the few chimneystacks in sight over peripheral skylines reveal that there are still local businesses providing beans to restaurants and traditional stores here. Consuming this product, which has a long history, is deeply embedded in the city’s day-to-day, but cultural shifts (today it is quaffed more at the bar rather than at home), means many of the old coffee shops are now obsolete.
