Those returning to Porto along the Luís I Bridge will notice a set of terraces to their right decorated with colored garlands, flags and string lights, as if someone forgot to take down their decorations after the June 23 São João festival, the city’s largest celebration. The garlands and flags stay up all year, though, and are the easiest way to find one of Porto’s most interesting hidden gems: the Guindalense Futebol Clube, home to some of the city’s best views. The story begins, at least officially, in 1976, when the club was founded as a place for amateur footballers and other athletes in the Guindais neighborhood.

Despite the fact that Porto has swelled with tourists in recent years, leading local establishments to evolve in order to cater to these visitors, there are thankfully many places that have swatted away all trends and remained faithful to their roots. In Miragaia, a typical Porto neighborhood that has resisted the pull of tourism, one can still find a place like this on each corner. A good example is Refúgio 112, which is located deep in the warren of narrow streets, where there are only houses and no awnings or anything notable to report. The restaurant is, as the name suggests, the refuge of Clarice Santos, or Clari for short. It opened eight years ago on the same day as the annual São João festival.

Caldo verde, Portugal’s most famous soup, doesn’t sound like much in English – “green broth” is the literal translation. I was thinking about this when reading an article on the 20 best soups in the world, which a friend sent to me, noting that caldo verde (a “homey soup” where “thinly sliced greens meld with potatoes and onions”) had made the cut. The article refers, in general, to the restorative power of soup, a belief that is held in very different cultures across the globe – which sounds about right to me. But then the author references a book that broadly defines soup as “just some stuff cooked in water, with the flavored water becoming a crucial part of the dish.” And I have to disagree there, because caldo verde is so much more than flavored water. How to explain that it is a feeling?

This is a day to do nothing. After a week of working from home, I’m facing another weekend of lockdown. Our restaurants are closed, and so are the bars – nowhere to get a drink. It’s raining outside, and I realize that I have chosen the wrong book to read: “The Winter of Our Discontent” by John Steinbeck makes the pandemic numbers even more difficult to bear. I open my computer and scan the news. Stopping to read an article about the selection of the year’s best Port wine, I remember that, yes, January 27 was declared International Port Day – a day for the world to celebrate this fortified vinho – a decade or so ago by the Center for Wine Origins, an organization in Washington D.C. At this point in time, I’ll take any reason to celebrate.

After the pandemic shook Porto’s restaurant sector like an earthquake, the city’s eateries are trying to rebuild themselves. Those who are still standing have opened their doors again and are now offering more than delivery and takeaway. In this city we live for contact with other people, talking face to face; nowadays that means imagining a genuine smile behind the mask. A well-known Portuguese expression may be one of the best descriptions for what restaurants are currently experiencing in the time of Covid: “Fazer das tripas coração” (“Making heart from the guts”). It means something like turning adversity into fuel, and in Portugal we use it to describe a superhuman effort. Because that’s what we’re all putting in currently, right?

On June 1, when Portugal entered the third phase of its lockdown exit, normalcy was still an elusive feeling. It was a mild Monday in Porto, the country’s second largest city, and the bars and restaurants that were open had few patrons. But as summer unfolded and cases remained low in northern Portugal, the city seemed to come back to life, with residents slowly recovering their routines, including going out to eat and drink again. Outdoor seating and terraces are especially popular, for obvious reasons. Canti, a bar on Largo Mompilher that was scheduled to open in March, finally flung open their doors in June but saw little demand for their indoor tables. “We have followed the government restrictions in our room inside, but everyone wants to stay in the outdoor area,” says Tiago Caetano, one of the owners. “Luckily we’re in the summer season,” he adds.

We went looking for Rogério Sá at his usual spot – his restaurant, Rogério do Redondo – but we were told at the counter that he just went “down there” to get “something” and will be back in a minute. “Down there” is with the men who fish in the Douro River. “Something” turned out to be shad – two fine specimens of the fish, in fact. “It’s in season,” Rogério tells us when he arrives. We know that fresh fish is worth the wait. The phone rings as we’re talking to Rogério, and he picks up. It’s someone calling for reservations – a party of six, and they’d like to pre-order the classic dish of rooster cabidela (where the meat is cooked in its own blood). “Let me talk to the cook to see if there’s any available, and I’ll call you back,” he says.

Lunch at Casa Guedes is one of our favorite culinary rituals in Porto: After snagging a seat at the bar during the midday rush, we sit, mesmerized, as Mr. Cesar nimbly cuts slices of roasted pork shank, then places them on bread and moistens it all with his secret sauce. While not the only item on the menu, the famous sande de pernil (roast pork sandwich) is Casa Guedes’s raison d’être. After taking in Mr. Cesar’s entrancing sandwich-making choreography, we order the upgraded version of the sande, which is topped with gooey queijo Serra da Estrela, a creamy sheep’s milk cheese. Seating at this humble and low-cost eatery used to be minimal, and Casa Guedes’s popularity had long outstripped its capacity – fans could be found waiting patiently in queues stretching down the block.

When it came to eating in Porto in 2019, not everything was new. The sheer number of restaurant openings in the city was overwhelming at times, so we often went back to the known places, just to make sure they were still there. It was cheering to see how many are preserving the flavors that we find so satisfying. And even though some spots have reinvented themselves, the food they put out continues to comfort our stomachs. “Veal with Grain” at Tasca Vasco Tasca Vasco is the younger brother of Casa Vasco, restaurateur Vasco Mourão’s namesake spot serving a mix of traditional Portuguese cuisine and international favorites in Foz do Porto.

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.

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.
