Metric Barcelona

Avinguda Diagonal is usually a place where dreams of authenticity go to die, swallowed by high-rise banks and the sterile hum of corporate commerce. But then there’s Metric. It sits there at number 505, looking less like a bistro and more like a high-end chop shop that decided to start serving tuna tataki. It’s big, it’s loud, and it’s unapologetically industrial—all concrete, iron, and exposed bones. This isn't your grandmother’s cozy tapas nook. This is a machine designed for eating, drinking, and eventually, losing your inhibitions to a DJ set.

When you walk in, the scale hits you first. It’s a 'Market-Bistro' concept, which in travel-speak usually means 'we sell overpriced jamón in the lobby,' but here it feels more like a functional workspace. The air smells of seared protein and citrus zest from the bar. It’s the kind of place where the lighting is low enough to hide your sins but bright enough to see that the person across from you is actually enjoying their meal.

The real story at Metric, the one that keeps the locals coming back despite the chaotic energy of the Diagonal, is the kitchen’s obsession with gluten-free dining. Usually, when a restaurant screams about being gluten-free, I want to run for the hills. It usually implies a sacrifice of texture, soul, and flavor. Not here. At Metric, nearly 95% of the menu is celiac-friendly, and they do it without making you feel like a patient in a clinic. The croquetas—those little fried nuggets of joy that are usually a minefield of flour—are crisp, creamy, and dangerously addictive. The Metric Burger is a thick, honest slab of meat that doesn't need the crutch of wheat to make its point. Even the breaded items have that satisfying, tooth-shattering crunch that usually requires a deal with the gluten devil.

But don't come here expecting a quiet, contemplative dinner. As the night progresses, the 'Piano Bar' and 'Cocktail Bar' labels start to make sense. The transition is seamless and slightly predatory. One minute you’re finishing a plate of grilled octopus with a decent garnish, and the next, the volume has ticked up three notches and a DJ is spinning tracks that make you realize you aren't going home at 10:00 PM. The cocktails are serious business here—not just sugar-water with a cheap umbrella, but balanced, punchy drinks that earn their keep on the bill.

Is it perfect? No. When the place is packed—which is often—the service can feel like a frantic game of Whac-A-Mole. You might have to wave a flag to get a second round of drinks, and the noise level can reach a point where conversation becomes a series of aggressive nods and 'What?' But that’s the trade-off. You’re in Les Corts, a neighborhood that can sometimes feel a bit too polished, and Metric provides the necessary grit. It’s a place for groups, for people who want to eat well without worrying about cross-contamination, and for anyone who thinks a meal is just the opening act for a long night. It’s honest, it’s functional, and in a city full of tourist traps, it’s a relief to find a place that actually knows how to throw a party without losing its culinary dignity.
