We kick off our Porto walk with the city’s favorite pastry, the éclair filled with whipped cream. It is so popular, the éclair was officially registered as The Sweet of Porto. We pair ours with a strong coffee for a soilid start to the morning.

Carla Santos is a busy woman. On the day we go to meet her, it is pouring rain in Porto and Adega Vila Meã, the restaurant she runs, is full. Carla doesn’t stop for a second: “One of those pork firecrackers with potatoes?” she asks a customer as she swings through the dining room. She’s not alone in this mad dash. Carla works the tables with her youngest daughter, while the oldest, who learned how to cook from her mother, mans the kitchen. Even Carla’s 7-year-old granddaughter helps out, clearing tables. “It costs nothing to start learning right now,” says grandma Carla, already certain that “we are moving Adega from one generation to the next.”

The restaurant that Inês Mendonça dreamed of can only be described using the Portuguese expression levantar as pedras da calçada – literally, to raise the stones from the sidewalk” –to create something totally new and groundbreaking. When Porto’s now-popular Ruas das Flores was being restored, the din of construction clanging as workers labored to turn it into a pedestrian-only thoroughfare, Inês was seeing miles ahead. It was there that her restaurant would open its doors, she decided, and it would be a place different from all the rest – relaxed and full of curiosities.

While on our Beyond the Barrell culinary walk, we popped into an old-school coffee shop for a cup of strong brew. Rustic spots such as this one are not far from century-old opulent Parisian-style cafes, sometimes staffed by tuxedoed waiters – it’s all part of the complexities and contrasts of life in Porto, which we dig into on our full-day culinary exploration.

You would think Sérgio Oliveira, the owner of Conga in Porto and the secret-keeper of its legendary recipe for bifanas, would be tired of the restaurant’s signature dish. But you’d be wrong. “As much as I try not to eat it, I cannot. It is impossible,” he says. "One always eats it; there is no chance not to.” It’s a simple but addictive dish. Pork, cooked all day in a mysterious spicy sauce and stuffed into a piece of bread that looks a bit like a roll– at first glance, it does not seem to impress. But Porto continues to hide the best and tastiest of its secrets in the simplest things in life. "It was my father who invented the famous bifanas with this wonderful sauce,” says Sérgio, who’s been running Conga the last eight years. It’s been more than 40 years since Manuel Oliveira returned to Portugal from Angola and opened the restaurant in 1976.

While Bolhão’s century-old original structure is being restored, the vegetables, fruits, fish and flowers of the market have been brought to a decidedly less striking indoor location with no windows. The place is new, strange to many, but the usual faces are there. We know their names, their smiles. The only thing we’re uncertain about is the setting. “It looks really beautiful,” says Rosa, “I thought it was going to be a mess, as it was something to remedy, but it’s beautiful.” Rosa tells us that she hasn’t been to Bolhão for at least a year, which is about how long the original location has been shuttered for renovation. As we walk with Fernando and Rosa, a chorus of “good days” rings out from all directions. We pass through corridors of fruit, nibble on some chorizo, smell the flowers. “Excuse me, where’s the herbalist Augusto Coutinho?”

On our Porto culinary walk we visit Luis at Azeitoneira do Porto, which has been serving loyal customers since 1862 - and is training the next generation to take over the family business.

We arrived at Taberna Santo António after lunch, looking for a bit of warmth in the middle of winter. It wasn’t a shot in the dark – we already knew that we would be enveloped by a comforting hospitality at this classic Porto spot. The sun was shining, so we sat on the terrace with Pedro Brás, whose parents own Taberna Santo António. “We’ve been here for 30 years in March,” he said. And while nowadays the surrounding landscape is inviting – just around the corner is the Parque das Virtudes, where crowds congregate in the late afternoon to listen to music, chat and drink beer as the sun sets over the Douro River – that was not always the case.

Thirty-year-old João Cura and his wife, 29-year-old Sofia Gomes, may be young but they have long had a wish to open their own restaurant. Yet it was never totally clear where or when they would fulfill this dream: both are originally from Coimbra, a city in central Portugal, and worked for years in Barcelona. The couple finally found a perfect spot, in Porto of all places, to open Almeja, which fittingly means “to want or to wish for something very much” in Portuguese. Talk about a dream come true.

Manuel Azevedo and Francisco Moreira, now both in their 70s, have been friends since childhood. Such a close connection has afforded them the trust and togetherness required to run O Buraco, the restaurant in Porto that the duo have presided over like generals for almost 50 years. In fact, it was right after completing his military service that Manuel, a native of Marco de Canaveses, a city within the greater Porto municipality, came to Porto proper in search of work. “I picked up the newspaper, saw the ad, applied and was hired as a waiter,” he tells us. On February 4, 1971, he entered O Buraco (“The Hole” for the first time; he hasn’t left since.

We were crawling through traffic on Porto’s ring road in our rental car when dawn finally caught up to us, illuminating the spectacular view of the Douro River down below. That slice of the waterfront quickly glided past as we exited the bridge, soon replaced by the lush rolling countryside south of the city: olive trees, low grape arbors. We were on our way to Santa Maria de Lamas to visit the headquarters of the world’s largest cork producer, Amorim Cork. Like most visitors to Porto, one of the first things we did upon arrival was a port wine tasting, perhaps the most famous feature of the city’s culinary culture. It was December 2016, and we had barely unpacked our bags before strolling down to the Douro River’s quays and finding a small spot to partake in this delightful ritual, one that has evolved over centuries.

After being named Best European Destination in 2017 and earning a few other tourist distinctions, there’s no doubt about it: Porto is trendy. But what’s trendy is also in Porto, and those who live here see new restaurants pop up every week. We try them all – places both bold and familiar – because we have a good appetite, but we put our trust in those spots where we get the warmest reception. And trust is something we take very seriously in Porto. Homey meals at A Cozinha do Manel Open now for three decades, A Cozinha do Manel is far from the touristy downtown and serves up good old comfort food, the type of fare that leaves us serenely satisfied.

“Where to eat in Porto?” Google search this sequence of five words and a multitude of articles listing restaurants and eateries will naturally come up as a result. Some of those suggestions – the trustworthy ones, at least – will mention Casa Nanda. It’s a fair choice: Casa Nanda is, indeed, one of the most traditional and historic joints in town. What most listings won’t mention, though, is that the couple who founded it and were its driving force are now working somewhere else.

The sensation of entering A Cozinha do Manel (“Manel’s Kitchen”) in Porto is so similar to entering grandma’s house on Sunday that it almost confuses us. There is no one to greet you at the door, no cloth napkins folded over employees’ arms. We walk confidently, as we would at home, with the sense of comfort that only intimacy is capable of inspiring. From the wall, among the many clocks, vintage plates and drawings made on cloth napkins by customers with an artistic bent, dozens of familiar faces look back at us. They are actors, musicians, politicians and soccer stars all standing next to Zé António, the owner and manager – a confirmation of the restaurant’s popularity.

Porto’s very old and emblematic Bolhão Market has been under renovation since May. Now working in a temporary building, the market vendors are feeling a mix of enthusiasm and apprehension about the new structure – they are mostly concerned with how different it will be and how much tradition will be lost.
