Nestled in an intimate chalet along Madrid's Manzanares River, OSA Madrid represents the pinnacle of contemporary Spanish gastronomy, where Michelin-starred chefs Jorge Muñoz and Sara Peral craft extraordinary tasting menus that honor tradition while embracing bold innovation. This secluded fine dining sanctuary, seating just 20 guests, offers an escape from the city's bustle into a world of culinary artistry.

The story of OSA begins with two exceptional talents who honed their craft at legendary Mugaritz before establishing their own culinary vision. Muñoz and Peral's philosophy centers on creating "the home of all Madrid" through cuisine that reflects identity, values, and honesty. Since opening, their dedication has earned critical acclaim including a coveted Michelin star and recognition as Tapas Magazine's Best New Restaurant 2023, establishing OSA among Madrid's finest restaurants.

The cuisine at OSA showcases wild, land-based gastronomy through two tasting menu options: an extensive 20-22 course journey or a focused 14-15 dish experience. Signature creations like red mullet amasake, oak-smoked brisket with juniper spice crust, and their renowned stuffed pig's trotter demonstrate masterful techniques in aging, smoking, and maturing. Each dish celebrates seasonal ingredients through precise cooking methods that amplify natural flavors rather than masking them. The chefs personally present raw ingredients tableside, explaining provenance and preparation methods that connect diners to their culinary philosophy.

The OSA experience unfolds across two floors of this charming riverside house, beginning upstairs in the wine cellar lounge where guests enjoy Spanish cava and house-made charcuterie beside a crackling fireplace. The main dining unfolds in elegantly appointed rooms featuring an open kitchen where culinary theater meets technical precision. The extensive wine program, curated with rare Spanish and international labels, provides thoughtful pairings that enhance each course. Service maintains exceptional standards throughout the lengthy tasting, balancing professionalism with the warmth of genuine hospitality.

For discerning gourmands seeking Madrid's most innovative fine dining, OSA delivers an unparalleled experience that justifies advance reservations. This intimate culinary sanctuary offers something truly special: a chance to witness two of Spain's most promising chefs at the height of their creative powers, crafting memories that linger long after the final course.
