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.

“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.

There has always been a bit of a rivalry between the two main cities of Portugal, Lisbon and Porto, which is well illustrated by an old running joke among some tripeiros (the name given to the people of Porto): whenever someone asks what is the best thing about Lisbon they will reply, “The highway sign that says ‘Porto.’” But it’s a healthy rivalry for the most part – football aside. Lisboetas, Lisbon locals, in general even tend to recognize that the food might actually be better in Porto and its surroundings, especially traditional dishes. While Porto does not benefit from the same multicultural influences that helped shape Lisbon’s restaurant scene, it is home to some very talented cooks with a knack for doing so much with so little.

Matosinhos, a small city just north of Porto, is used to change. It has an industrial air to it, due to its 19th-century harbor, and its past prosperity was connected to the fish-canning sector, which peaked during World War II and declined from the beginning of the 70s. The numerous abandoned warehouses attracted nightlife during the 1990s, with clubs finding a fertile zone for noise. The completion of the long-delayed tidal pool, built by Portugal's starchitect, Alvaro Siza (who was born in the city), put it firmly on the map again after the project was delayed for decades. In January, the launch of the new, spiralling cruise ship terminal added to the contemporary design-y feel that has been developing on its otherwise rugged coastline.

A gloppy, meaty, cheesy brick served in a pool of sauce and with a mountain of fries: please meet the francesinha, the culinary pride and joy of the city of Porto. Today, restaurant billboards proclaim in many languages that they serve the best version in the world, revealing the genuine power of this artery-clogging combination that, incredibly, was originally conceived as a snack. We have to say it though: eating a francesinha is worth every last calorie. This dense sandwich, which is impossible to eat just with your hands, is often considered the lusophone version of the croque monsieur.
