About Sushi Omakase
Hidden behind an unmarked door in Ibiza town, Sushi Omakase by Walt delivers an Edomae-style experience that rivals Tokyo's best, with just eight to eleven seats at a sleek wooden counter where chef Walter Sidoravicius orchestrates each course. The speakeasy-inspired setting amplifies the sense of discovery—intimate, hushed, and entirely focused on the ritual unfolding before you. Recognized with one Michelin star, this is pure omakase in its truest form: no menu, no choices, just trust in the chef's mastery of high-grade fish and perfectly seasoned rice. For serious sushi devotees seeking authenticity on an island better known for beach clubs than traditional Japanese technique, this is your destination.
Good to know
Book well in advance—the eight to eleven seats fill quickly, and walk-ins are essentially impossible during high season.
The chef
Walter Sidoravicius
Walter Sidoravicius has been working in restaurants worldwide since 2008, with formative years spent at Nobu Tokyo where he absorbed the rigor of Edomae tradition and high-volume precision. He later served as an instructor at the Basque Culinary Center, shaping the next generation of chefs, and has consulted in Marrakech, Vienna, New York, and Barcelona, bringing technical depth to diverse markets. A finalist at the World Sushi Cup 2014, Walt's approach is rooted in classical technique but informed by years of cross-cultural exchange, resulting in omakase that honors tradition while reflecting his global experience.
The Insider Compass
Four dimensions, each assessed independently against the same criteria everywhere we rate.
Plate
Walt's command of Edomae technique shows in every piece—the rice is properly seasoned with a subtle acidity that complements rather than competes, and the neta (fish topping) arrives at peak temperature and texture. His time at Nobu Tokyo and years consulting across global kitchens translate into nigiri that balance tradition with precision, each bite calibrated for umami, fat content, and mouth feel. The progression builds intelligently, moving from delicate white fish to richer, more assertive cuts, with impeccable knife work evident throughout.
Vibe
The counter-only format creates a zen-like focus—no tableside chatter, no separate dining rooms, just ten or fewer guests watching Walt work in near silence. It's intimate to the point of meditative, though the energy shifts depending on your fellow diners; a gregarious group can alter the tone. The speakeasy conceit adds theatrical flair without feeling gimmicky, reinforcing the sense that you've stumbled onto something special.
Service
Walt himself guides the experience, explaining each piece with quiet authority and reading the room's pace instinctively. The front-of-house team is equally attuned, offering sake pairings that shift with the menu and maintaining seamless timing between courses. It's hospitality rooted in knowledge, never stuffy, with a warmth that makes the formality of omakase feel approachable.
Setting
The minimalist counter and warm wood tones evoke a traditional sushiya, stripped of distraction and designed to keep your attention on the cutting board. Tucked on Via Romana in the heart of Ibiza town, the unmarked entrance reinforces the speakeasy vibe, making arrival feel like initiation into a secret. The space seats so few that the design barely needs to assert itself—simplicity is the point, and it works.
These four dimensions are a handful of the attributes we review. The Insider Rating also draws on research the compass does not display — among them the wine programme, the size and quality of the cellar, the location, and how long the house has operated. It is not an average of the scores above.
Go for
- Authentic Edomae-style sushi that stands comparison to Tokyo's top counters
- An intimate, speakeasy-inspired setting with counter seating for ten or fewer
- Michelin-starred precision on an island where serious Japanese technique is rare
Don't go for
- Creative fusion or American-style rolls—this is traditional nigiri in the purest sense
- A lively, social night out with a large group; the intimate format demands quiet focus
