As one approaches the central square of Kalyvia, a small village only 10 minutes from Athens International Airport, the irresistible smell of grilled meat fills the nostrils. The whole area is packed with traditional grill houses, and many Athenians will make the 45-minute drive just to enjoy a meal there. The oldest taverna and one of the most famous is Kollias, which still boasts the traditional butcher shop that gives these grill houses their Greek name (hasapotaverna, or “butcher taverna”). Anastasios Kollias opened the place in 1930 just up the road, but it gradually became too small to accommodate the growing clientele, so it took its current spot on the square in 1991.

In Athens, the traditional way to roast a lamb is right on the street. This age-old practice may be encountered during our Backstreet Plaka tour.

Crete, Greece’s largest island, is among the country’s most beautiful and interesting places to visit. Well known for its amazing beaches and unforgettable cuisine, the island also has a long history of wine making, dating back more than 4,000 years. The ancient Minoan civilization was one of the first to be deeply connected with wine. Viticulture and wine making are depicted on paintings in the Minoan palace of Knossos, while ancient wine presses have been found all over the island, with the world’s oldest in Vathypetro, just a few kilometers outside Heraklion, the capital. The Minoans were the world’s best-known merchants of the time, and amphorae carrying Cretan wine have been found in digs all over the Mediterranean basin.

We had to share this lovely photograph taken by Don Kedgley at Diporto, a basement taverna that has been around since 1887 and ranks among our favorite spots in Athen

The oranges are beckoning shoppers at the farmer's market in Keramikos, central Athens. This market is a featured stop on our downtown Athens tour. Already pleasant and bustling in March at the time of this photo, imagine what it's like in May!

It must be one of the world’s oldest cheeses, it’s certainly one of the most famous, and it’s practically never missing from a Greek table, no matter the time of day. A person might grab a chunk of this chalk-white substance for breakfast, crunch through layers of feta-stuffed phyllo for elevenses, put a slab of it on her village salad for lunch, have it for supper along with a vegetable casserole and then pair it with watermelon for a scrumptious dessert. The only other food that a Greek may be even more addicted to is bread. If you were to guess which nation boasted the most cheese eaters on the planet, surely you would say France, home to so many delectable and sophisticated fromages.

The oldest taverna in central Athens features delicious and simple food all prepared by Mr Dimitris, who has been running it since he was a child! This is a place one may stumble into on our Downtown Athens walk.

It's the season of fresh garlic! Garlic at its best. This basic ingredient of Greek cuisine can be found fresh at the markets encountered on our Athens walks, and now is the best time to snag a stalk.

Wild greens or horta (χόρτα) are an ancient and still very important ingredient in traditional Greek cuisine (and happen to have exceptional nutritional value to boot). Every season brings different varieties: some more bitter, some milder and sweeter, some naturally salty, all with different textures and shades of green. Almost every single taverna around Greece includes horta in the salad section of the menu. These boiled greens served with virgin olive oil, sea salt and plenty of freshly squeezed lemon juice are one of the most common salads enjoyed throughout the year, usually with fish, but sometimes also with meat. When eating out, Greeks typically ask the waiter what type of horta the restaurant serves, as they know it depends on season, region and availability of each variety.

This row of coffee beans, roasted and then grinded, is enough to wake up an entire city. One might stumble upon such a scene on our Culinary Secrets of Downtown Athens tour.

The first and most vivid impression one has of Piraeus is its port: bustling, ugly and uninviting. Just a place you have to endure in order to get to your destination, usually a beautifully serene Greek island. Piraeus, however, is definitely an exciting place for anyone looking for a culinary adventure, as it is a melting pot of cultures with many interesting places hidden in the backstreets, away from tourists. The whole area next to Hadjikyriakeion for example, a girls’ orphanage built in the 19th century, is well known to locals for its humble, yet high-quality tavernas, serving fresh fish and simple meze all year round.

The working-class area of Brahami has never been Athens’ hottest gastronomic destination. It is a mostly residential neighborhood, halfway between the city center and the exotic beach-loving southern suburbs. Like most of the city’s suburbs, in the not-so-distant past, this area was once made up mostly of fields. Now formally named Agios Dimitrios (St. Dimitrios, after St. Dimitrios’s church), it has a vibrant local market. It’s also home to Remoutsiko, a family-owned, family-friendly taverna focusing on meat. Housed in an old converted barn, the restaurant has been around for some 30-plus years.

All over Athens (not to mention the U.S. and other parts of the world), one of the hottest grains around is also among the oldest known to man. While farro, or zea, as it’s known in Greek, has been found in excavations of prehistoric settlements in parts of what was once Ancient Greece (the oldest, in Asia Minor, dating back to 12,000 BCE), in the early 20th century, its cultivation was banned, largely because it was cheaper to import other grains (though many incredible conspiracy theories behind the ban abound). Thankfully, zea began making a comeback about 15 years ago, and it is now popular again, not just in grain form, but also as flour for making baked goods and pasta.

A wide variety of reasonably priced fresh fish, shellfish, crabs and kalamari for the customers to choose at the Athens Municipal Market, a stop on our Culinary Secrets of Downtown Athens walk.

On our Plaka walk, this four-legged friend was begging for food, so we couldn't help but share some of our sheep's milk yogurt. We are expecting more animal followers on our Athens walks from here on out.
