This is the Madrid tavern that time forgot — and we mean that in the best way. Since 1860, Casa Labra has been serving up bacalao (salt cod) and croquettes to standing-room-only crowds just steps from Puerta del Sol, barely changing a thing in over 160 years. It's also where the Spanish Socialist Workers' Party was founded in 1879, so you're literally eating history alongside your tapas. Skip the tourist traps on the square and come here instead.
Standing-room-only since 1860, this tiled tavern near Sol serves Madrid's best bacalao croquettes — and happens to be where Spain's socialist party was born.
Go before 1pm or after 4pm to avoid the worst crowds — the line forms at the street and moves fast, but the marble bar fills up quickly at lunch.
1860 tavern where Madrid's bacalao obsession was born
Casa Labra is the kind of place that makes you understand why Madrid's taberna culture is so beloved. Founded in 1860 by an Asturian immigrant, this spot has been slinging bacalao — salt cod — for over a century and a half, and they've gotten very, very good at it. The cod croquettes are the thing to order: golden, creamy on the inside, with that unmistakable salty punch of quality bacalao. You eat them standing at the marble bar or perched on a stool, surrounded by tiled walls and the ghosts of every madrileño who's passed through since the 19th century.
The history here is no joke — this is literally where Pablo Iglesias founded the Spanish Socialist Workers' Party (PSOE) on May 2, 1879, and Federico García Lorca was reportedly a regular. But what keeps the place packed isn't the trivia, it's the food. The fried bacalao strips, the croquettes, the tapas de bacalao — all cheap, all honest, all exactly what you want with a cold caña (small beer) at 1pm on a Tuesday. The split between the standing bar area and the small back dining room means you can do a quick bite or a slightly longer sit-down.
Here's the thing though: it gets crowded. Like, really crowded. The location near Puerta del Sol means tourists find it, but locals keep coming back too, which tells you everything. Go early or go off-peak if you want to actually breathe. The toilets are famously tiny and the whole place is no-frills, but that's the point. You're not here for ambiance — you're here because this is one of the last authentic century-old taverns in central Madrid, and the bacalao is worth queuing for.
