Çukur Meyhane, a small, slightly shabby basement meyhane in Beyoğlu’s Galatasaray area, certainly does not look like the kind of place with any shining stars on the menu. On one of our very first visits, the floor seemed to be covered in a mixture of sawdust, table scraps and some cigarette ash. The tiny open kitchen occupies one corner, while the VIP table – where a group of old-timers can be found watching horse races on TV, scratching at racing forms, cursing and cheering – takes up a slightly larger area. A good bit of the other half of the room is home to a giant ornamental wooden beer barrel.

If Istanbul's old city represents its ancient and imperial history, the center of the city's Beyoğlu district is the heart of its modern past, present and future. As tumultuous as the first century of the Turkish Republic, Beyoğlu is in a constant state of flux. It is the heart of culture and entertainment in Istanbul, and still carries the air of the cosmopolitan area it once was. Its impressive array of gorgeous turn-of-the-century European-style buildings is matched by no other area of the city. While a recent process of crass commercialization has turned many people away from Beyoğlu, it is making a resurgence, evident by thriving meyhanes and watering holes such as Marlen and the recently-opened Sendika, a sleek, enthralling space with a bar/restaurant below and dance floor above where DJs spin five nights a week. For us, Beyoğlu is always the place to be, positive or negative changes notwithstanding.

Sausages and beer might not sound much like a Tbilisi affair, but this most Bavarian of combinations is what has been served up steadily for more than five decades in one of the city’s oldest watering holes. Nodar Vardiashvili and his shop have survived the collapse of the Soviet Union as well as the tumultuous decade of civil war and economic devastation that followed. Through the roiling changes that transformed the wider region and the skyline of Tbilisi as better economic years returned, little changed in the metal-clad, bunker-like establishment in the neighborhood of Nazaladevi that has been slinging sausages and pouring beer (and sweet fizzy lemonades) since 1964.

Back in the day, according to legend, a man named Köpoğlu spent all his money on rakı, the Turkish spirit made from grapes and anise, and was left with no money to buy food. Hungry, pockets empty, he went home and grabbed a couple of eggplants, some tomatoes and garlic from his garden and threw them onto the coal fire of his grill. He then mixed together garlic and yogurt as a sauce and combined it with the grilled vegetables to eat alongside his rakı, inventing one of the most famous meze dishes in Turkey and Mediterranean. Today in Turkey, we can be sure that summer is here when eggplants and tomatoes appear together in abundance on market shelves. Especially when topped with garlic yogurt, these two vegetables make an exceptionally fresh and tasty combination.

It’s Friday at Little People’s Place in the Tremé, and that means fried fish. Rodney Thomas carries a tray laden with freshly battered shrimp and catfish fillets out the bar door to his provisional fry station, a well-worn propane burner with a heavily seasoned cast-iron dutch oven on top. The oil inside the dutch oven begins to shimmer and circulate, and Thomas drops a pinch of the seasoned fish fry into the cauldron-like pot to see if the oil is hot enough. A quick sizzle confirms it is, and Thomas begins to nimbly slip the shrimp and catfish into the hot oil, which bubbles vigorously. A few feet away under the plywood awning that covers the entrance to the bar, a group of men are watching daytime television on a small flatscreen TV sitting on an outdoor table – today it’s Divorce Court – while slowly sipping beers.

In Italy, family is everything. And in Palermo, every family has a fisherman. These concepts are present on Trattoria Piccolo Napoli’s red, blue and white sign, which sports a caricature of a perplexed sea bass and a promise of home cooking. Open the wooden doors to find a three-generation seafood restaurant a stone’s throw from the city’s old harbor with a fantastic fresh fish display, with part of a swordfish sitting high on the icy altar, below a bowl of lemons.

As one of the unsung heroes of traditional foods in Los Angeles, soondae (also known as Korean blood sausage) is having a resurgence in popularity, thanks to culinary pilgrims who make it their mission to visit Los Angeles, a city known for some of the trendiest and best-tasting Korean restaurants outside of South Korea. Wedged into the corner of a strip mall between a beauty salon and a print shop, the tiny Eighth Street Soondae, beloved by the Koreatown community since 1990, is possibly the best place in L.A. to try the dish.

In 1683, so the story goes, an Austrian Jewish baker wished to honor King Jan Sobieski of Poland for repelling an invading army. The king was renowned as a horseman, and so the baker shaped a ring of dough into the shape of a stirrup – a beugel. That origin story might be impossible to verify, but the bagel is inextricably entwined with the culinary history of Eastern European Jews – and, thanks to immigration in the 19th and early 20th centuries, with the culinary history of New York City Today, of course, bagels are consumed not only within New York's Jewish communities but throughout the city – and the United States – as standard American breakfast fare. Commercially packaged and, typically, frozen, bagels are displayed and sold in the same chain stores that sell brand-name sliced bread. But while they might adhere to the basics – yeasted dough shaped into a ring, briefly boiled, then baked – these mass-market bagels are factory-made.

Restaurants aren't hard to come by in Tbilisi, but it is harder to find places that feel like eating in your grandmother’s living room. Walls lined with family photographs fading from color to black and white, an eclectic collection of paintings, a whole window dedicated to religious icons, and a menu that can change on a whim. This is Nikolozi, a tiny restaurant in Sololaki run by Dodo Ilashvili, a singular powerhouse who creates the food and the feeling all herself.

For me, some of my favorite dishes when I return to Lisbon are the following: Rissois de camarão – prawn rissoles Grilled Alentejo pork plumas with a tomato salad and piri piri. These are the dishes that make me salivate when I fly back home. Both of them symbolize the food of Lisbon and they always taste better in situ.The pork dish is one you can find with reasonable quality in most good tascas or old school eateries throughout the city. I prefer to sit outside to soak in the sun, perhaps because I now live in London where there’s so little of it.

Among the many legends about pizza in Naples, the most famous and widespread – even though widely confirmed as inaccurate – is the one about the birth of the margherita pizza. Time and time again the story has been repeated, according to which this most beloved pizza was born in the summer of 1889, baked at the Capodimonte royal palace. Made by the cook and pizzaiolo Raffaele Esposito of Brandi Pizzeria, the pizza was intended as an homage to Queen Margherita di Savoia, wife of the first king of Italy (as a united nation) Umberto I, and to the country's three-colored flag.

Summer markets in Marseille come alive, bathed in a colorful, brilliant bounty when fruits and vegetables are in their prime. There are over 25 open markets in Marseille and every Saturday, our mornings are booked. We set out to one of our neighborhood favorites, the market at Place Sébastopol in the town center, to search for a particular treat. A summertime market grandstander is the fleur de courgette, or zucchini blossom. This gorgeous, bright yellow-orange edible flower is in season from May through September. The blossoms are prepared in almost every way imaginable, as toasty beignets (fritters) or farcis, stuffed flowers that contain meat, rice, cheese and vegetables bathed in tomato sauce. Zucchini blossoms can also be eaten raw, and are delicious in a summer salad.

Some parts of the Mitaka Chige Club’s name obviously ring true. It is one of many restaurants and bars clustered around Mitaka station’s North exit. Jiggae (often written “chige” in Japanese katakana), a shockingly red Korean soup with a gochujang base, occupies a substantial portion of the main menu. The “club” aspect becomes evident with the palpable feeling that this whole experience is carried by a small group. Passionate individuals on both sides of the counter are the lifeblood of the Mitaka Chige Club.

Las Chiquihuitas is a relative newcomer to Oaxaca’s organics scene that celebrates its two-year anniversary this month. A tiny sliver of a corner store located right smack-dab in the city’s historic center, the shop manages to pack a surprising amount of organic, local and lovingly produced foods within the diminutive confines of its four walls. A quick examination of Chiquihuitas’ lone refrigerator turns up a candy-colored array of seasonally flavored kombuchas and ginger beers stacked above a selection of buffalo milk butter and cheeses sourced from the Oaxacan coast, plus chunky glass jars of ferments ranging from classic sauerkraut to spicy kimchi. The store’s selection of dry goods might include shiny black beans, sticky, dark-brown blocks of the unprocessed sugar known as panela and jugs of fragrant virgin coconut oil. Happily, there’s a robust lineup of fresh produce, too, with juicy tomatoes, spiky pineapples and nubby potatoes peeking out of the black plastic crates dominating one of the store’s shelving units.
