Think of Blavis in the Sant Gervasi neighborhood as the restaurant equivalent of the iconic Fiat 500 or Mini – perfect for a crowded city and charmingly so. Even though there are only two regular members of staff, this tiny spot packs a powerful punch. Chef and co-owner Marc Casademunt crafts tapas-style plates influenced by local and international cuisines, which are then served by Paco, the friendly waiter. When Marc and his partner, Sonia Devesa, opened the small restaurant in 2008, the financial crisis informed their initial concept: offering an affordable daily lunch menu for workers. In the beginning, they only opened for dinner two nights per week.

Three humble ingredients – potato, cabbage and bacon – that’s all it takes to cook trinxat, the quintessential Catalan wintertime comfort dish. Potatoes and cabbage are boiled and mixed with fried bacon, and everything is cooked as a mash in a pan until it resembles a potato omelet. Its simple ingredients and even simpler preparation are exactly what make this dish so delicious. The equivalent to the British bubble and squeak, trinxat means “chopped” or “shredded” in Catalan. The relatively high altitude of Andorra and the Catalan Pyrenees brought with it harsh winters, food shortages and long periods of isolation, so in the past, people living in the region had to come up with a recipe that could help them cope with the adverse conditions.

Years ago, when it was a booming industrial center, Poblenou saw thousands of workers stream in every day to toil away at one of several factories in the neighborhood. Hearty fare was required to keep them going – sure, taste mattered, but sustenance was the most pressing concern. Poblenou may no longer be filled with factories, but there are still plenty of people who spend their weekdays in the area, working at one of the many start-ups, tech companies or communications firms that have set up shop in their place. When it comes to lunch, these 21st-century workers want the same thing that those who came before them did: lunches that fill their stomachs and satisfy their taste buds without leaving a big hole in their pockets.
