Dear Culinary Backstreets, I heard from some friends that everyone smokes in restaurants in Athens, despite the fact that it is not officially permitted. What is the situation, and is there anywhere we can dine without being exposed to smoke?

Dear Culinary Backstreets, We will be visiting Barcelona with our children. Do you have any good recommendations of places in the city to eat with kids?

Kadınlar Pazarı – a pleasant, pedestrian-only square in Istanbul’s Fatih neighborhood – is the closest thing the city has to a “Little Kurdistan.” The area is populated by migrants from Turkey’s predominantly Kurdish southeast region, and small market stalls and butcher shops selling honey, cheeses, spices and other goodies from the region surround the square. Visiting the atmospheric area is a great way to get a taste of Southeast Turkey without having to leave Istanbul.

In a 2003 TV commercial for Cola Turka, the actor Chevy Chase was seen speaking Turkish and then sporting a moustache, after taking just one sip of the intended challenger of Coke in this country. This sensational ad – which riffed on the old theme of American cultural imperialism through its number-one agent, Coca-Cola – was the first time that Turkish soft drinks caught our attention. Though we didn’t take to the overly sweet Cola Turka, we did start looking beyond, to its local brethren in the market: gazoz, a world of nearly extinct Turkish carbonated drink brands with a fanatical following.

Once a resort town on the outskirts of the Greek capital, Phaleron – only a few miles from downtown Athens – is now well incorporated into the city’s urban fabric. The area has remained an upscale neighborhood, but, sadly, it has lost its distinctive character: the sea is now polluted, the open-air cinemas have been turned into parking lots, and many of the stately mansions were demolished to make way for apartment blocks during the construction boom of the 1960s.

One of our favorite markets in Mexico City, Mercado Jamaica is a fantastic destination any time of the year, offering everything from festive Christmas decorations to a large selection of fruits and vegetables. After the markets of Xochimilco, Jamaica is also one of the city’s best flower markets, with block-long aisles filled with freshly cut flowers and plants of almost every imaginable color and type. But as much as we love getting lost in the sweet scents of these green alleyways, what keeps us coming back to Jamaica is El Profe, an excellent eatery inside the market that specializes in barbacoa. El Profe ("The Prof") looks less like your typical market food stand and more like a mini restaurant, with small brass chandeliers hanging from the ceiling that provide more in the way of ambiance than actual light. Waiters and cooks in matching blue uniforms hustle and bustle around the customers, who come and go from the counter at a steady pace.

De toda la vida is a Spanish expression that basically means “It’s been around forever,” and it’s a sure thing that the locals in Barcelona’s Gràcia neighborhood will utter those words if you ask them about Bodega Quimet. Opened in the 1950s by the Quimet family, the bodega (not to be confused with Quimet i Quimet, a popular Barcelona tapas bar) was passed down from father to son until 2010, when the younger (but nonetheless old) Quimet retired and brothers Carlos and David Montero bought the venue. David Montero had always worked as a cook and dreamed of owning his own place. However, after buying Quimet, instead of doing the renovations so typical of Barcelona bars that change hands (such as modernizing the furnishings or installing a huge flat-screen TV for showing fútbol matches), the Montero brothers made the somewhat unusual decision to keep everything, from the low prices to the décor, pretty much the same as it always had been.

Dear Culinary Backstreets, I keep hearing about Greek coffee but is it any different from Turkish coffee? And do most Greeks actually drink Greek coffee these days or do they drink other types of coffee? Greek coffee is exactly the same as Turkish coffee – and it was in fact called just that in Greece until Turkey invaded Cyprus in 1974, at which point, for political reasons, the Greeks decided to rename their coffee “Greek coffee.” The process and preparation, though, are identical to the Turkish way.

The economic crisis that has plagued Greece for the past five years has led to changes on the Athenian culinary scene, including the opening of three new types of venues that seem to be reflective of the times. The first two – cupcake places and frozen yogurt shops – are imports from abroad, perhaps indicative of a population in need of something sweet, comforting and affordable. On the other hand, the third trend, wine bars, digs deep into Greece’s roots, representing a fascinating phenomenon in a country that is one of the world’s oldest wine-producing regions. In antiquity Greek wine was exported across the Mediterranean, and the winemaking tradition has remained strong through the millennia. Yet although there are numerous wineries around the country, in the modern era Greek wine has never achieved the place it deserves on the international market. Production levels are low and vintners have long been unsure of how to market abroad.

The Turkish proverb “At, avrat, silah ödünç verilmez” (“neither horse, wife nor weapon should be lent”) is sometimes repeated as a way to recall the nomadic warrior past of the Turks. The primal Turkish essentials are clearly stated, but what about the çay bardağı, the tea glass that has become such a ubiquitous Turkish icon? Reading the 17th-century works of Evliya Çelebi, the Ottoman Rick Steves, you’d expect to find descriptions of medieval tea jockeys swinging trays filled with those tulip-shaped glasses through the alleyways of the Old City. Right?

Dear Culinary Backstreets, We’ll be visiting Mexico City and are wondering about the organic food scene. Will it be easy for us to find organic produce? How can we know whether or not something we’re buying is really organic?

As the legend goes, a 19th-century Catalan farmer was out experimenting in his fields when he came up with a new kind of longer, juicier green onion, the calçot. In creating the onion, the farmer produced much more than a new vegetable; he also paved the way for the rise of an idiosyncratic, and distinctly Catalan, cultural event.

Good service in China is a relative term, and the longer you live here, the lower your expectations sink. The Michelin Guide allegedly won’t deign to cross over the Hong Kong border into China because they refuse to sully their white-tablecloth reputation by doling out stars to restaurants with subpar service. But the inspectors must have never entered a Hai Di Lao Hot Pot, or they might have to change their tune.

Until we visited some of Istanbul’s shrines to the baked bean, we generally regarded the dish as something eaten out of a can beside railroad tracks. But Turkey takes this humble food, known as kuru fasulye, seriously; that means chefs in tall toques carefully ladling out golden beans in a rich red gravy onto monogrammed flatware, served by waiters wearing bowties and vests. Even in the least formal of Istanbul’s beaneries, the guy manning the pot has the air of a high priest who knows that his incantations alone conjure something unusually delicious out of a simple dry white legume. This is no hobo fare.

Dear Culinary Backstreets, I’ll have an eight-hour layover in Istanbul and was wondering if you have any suggestions for places to go for a good Turkish breakfast and lunch. I love to eat at small, local places serving authentic food. I would prefer restaurants in the Yeşilköy area, as I have to be back at Atatürk Airport to board an international flight (which I cannot afford to miss!).
