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.

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.
