Zarate

Sergio Ortiz de Zárate opened Zarate in 2012 on Licenciado Poza, the spine of Bilbao's Abando business district, and won his Michelin star three years later. The restaurant is a 32-cover room with a kitchen counter, a wood-fired grill visible behind glass, and a commitment — near-monastic in its discipline — to fish and firewood. The menu changes day to day based on what came in on the Bermeo and Ondarroa boats that morning.

The cooking is radically simple. A whole turbot, grilled whole over oak and served with a single brush of garlic-and-Espelette oil. A red mullet, grilled at very high heat for exactly 90 seconds per side. A hake cheeks, poached in their own collagen with pil-pil sauce. There is no tasting menu; ordering is a conversation with the sommelier-owner about what's in the cold room that evening. Typical dinner is three to four courses at €85–140 depending on the fish selected.

The wine list is short (180 references) but extremely precise — strong on Txakoli from the four DOs, a deep Rioja Alavesa selection, and a few cult Ribeiro whites. The sommelier will pair by the glass on request. Service is led by Ortiz de Zárate's wife Isabel, who has run the floor since opening.

The room is quiet at lunch — the clientele is heavily lawyers and bankers from the surrounding professional firms, often negotiating — and lively at dinner. The four-seat counter facing the grill is the best solo-dining position in the city.

Zarate is Bilbao's preferred business-lunch room for a reason — the cooking is simple enough that no one has to defer to the menu, the room is quiet enough that a lawyer can work through a term sheet across the table, and the wine list is deep enough to reward an attentive host. For deal-closing lunches, book the back banquette at 13:30. The standard pattern: two starters shared, a grilled whole fish for the table, a Txakoli from the current vintage, no dessert, coffee. Ninety minutes, invoice-friendly, quietly impressive.
