About the Vibe
This is a one-trick pony that nails the trick. Since 1964, the Nieto family has been grilling champiñones stuffed with chorizo, garlic, and parsley on a plancha just steps from Plaza Mayor — and that's basically all you need to order. The cave-like dining room is pure Madrid castizo: tiles, ham legs hanging overhead, and a crowd that ranges from locals on a lunch break to tourists who somehow found the right place. Skip everything else on the menu and focus on what they do best.
Why it's worth it
Since 1964, this cave-like mesón near Plaza Mayor does one thing — champiñones stuffed with chorizo, grilled to perfection — and does it better than anyone.

One dish, sixty years, zero compromise
Let's be clear: you come here for one thing, and that's the champiñones. Whole mushrooms grilled on a plancha, stuffed with a nugget of chorizo, and finished with garlic, parsley, olive oil, and a squeeze of lemon. That's it. The simplicity is the point — and after 60 years, the Nieto family has this down to a science. Order a plate (or three), stand at the bar or grab a table in the cave-like dining room, and don't overthink the rest of the menu. Multiple reviewers confirm: stick to the mushrooms and you'll leave happy.
The setting is classic Madrid castizo — tiled walls, jamón legs dangling from the ceiling, and a constant buzz of locals and tourists alike. It's on Cava de San Miguel, just a few steps from Plaza Mayor, which means it gets packed. The downstairs dining room has a certain old-school charm, though some reviewers note it can feel cramped and the service rushed when it's busy. Pimientos de Padrón are a solid side if you want something green.
Is it the best food in Madrid? No. But it's one of the most authentic mushroom experiences you'll have, and at this price point, in this location, it's hard to beat. Go early or go off-peak — the line forms fast and the place is small. A 4.4 rating across 6,000+ reviews tells you they're doing something right.
