In the heart of Spain’s northern coast, Casona del Judío in Santander stages fine dining within a romantic 19th-century colonial mansion, fusing maritime soul with modern precision. This Michelin-starred address seduces with chef Sergio Bastard’s hyper-local vision—an ode to the Cantabrian Sea, coastal algae, and wild herbs—making Casona del Judío + Santander synonymous with refined, place-driven gastronomy delivered in an atmosphere of quiet exclusivity.

The Story & Heritage
Housed in a lovingly restored casona, the restaurant channels Santander’s seafaring heritage through Bastard’s contemporary lens. Trained across Spain’s top kitchens, the chef distills years of technique into a singular culinary philosophy: amplify origin, respect seasonality, and surprise with restraint. Casona del Judío has earned a Michelin star for its originality, terroir focus, and faultless execution. Guests begin in a dedicated snack salon, where Bastard personally introduces the narrative of the meal—an immersive prelude that underscores the house’s devotion to craft, education, and hospitality.

The Cuisine & Menu
Expect a resolutely modern tasting menu—the Festival—guided by the tides and the forager’s basket. Bastard’s hallmark Salmuria, an anchovy brine matured and bottled in-house, threads through sauces to deepen flavor with crystalline salinity. Highlights evolve with the market: oyster with coastal algae and herb emulsion; red mullet glazed in Salmuria with sea fennel; milk-fed lamb with rock samphire jus; and a playful Cantabrian milk dessert scented with marine botanicals. Sourcing privileges small fishers, sustainable purveyors, and producers across Cantabria. The restaurant accommodates common dietary needs with advance notice, maintaining the tasting’s narrative while honoring guests’ preferences. Price positioning is fine dining with ultra-premium touches.

Experience & Atmosphere
Original stonework, timber beams, and soft coastal hues meet sculptural ceramics and tactile linens—a dialogue of history and modernity. Service is polished, intuitive, and choreographed without fuss, with a team fluent in the kitchen’s techniques and provenance. A thoughtful wine program—anchored by Spain’s rising vintners, classic Rioja and Ribera, and a global selection of Champagne and Burgundy—offers curated pairings led by the sommelier. Seek out the chef’s opening snack room ritual, private dining salons for intimate celebrations, and occasional chef’s table experiences. Expect smart-elegant dress. Reservations are essential due to limited seating; the Festival tasting is the primary path, with an optional wine pairing and a refined aperitif program in the lounge.
