Restaurant in Buenos Aires, Argentina
Michelin-recognised omakase. Book weeks ahead.
Uni Omakase is Buenos Aires's most credentialed omakase counter, holding Michelin Plate recognition in both 2024 and 2025 and a 4.7 Google rating across 446 reviews. At $$$$ pricing in Palermo, it is a hard booking suited to special occasions and serious food itineraries. Reserve three to four weeks out minimum.
Uni Omakase holds a 4.7 Google rating across 446 reviews and back-to-back Michelin Plate recognition in 2024 and 2025. That combination tells you something direct: this is not a novelty Japanese restaurant for a city short on options. It is a genuinely credentialed omakase counter on Guatemala Street in Palermo, and it competes on quality terms that go well beyond its local category. If you are deciding whether to commit at the $$$$ price point, the Michelin acknowledgment and the rating volume together give you reasonable confidence the kitchen delivers consistency, not just a few great nights.
Buenos Aires has a small but growing cohort of serious Japanese dining rooms. Uni Omakase sits at the leading of that group alongside Buri Omakase, and the two are the venues worth comparing directly if omakase is your format. Uni's Michelin Plate credentials give it an edge in verifiable recognition, but both counters demand advance planning and a willingness to spend at the upper end of Buenos Aires dining. For broader city context, see our full Buenos Aires restaurants guide.
Omakase as a format means the kitchen sets the pace, the sequence, and the portion count. You are not ordering; you are committing to a chef-driven progression of courses, typically anchored in Japanese technique with fish and seafood at its center. At $$$$ pricing in Buenos Aires, that commitment is significant in local terms — this is among the most expensive meals you can book in the city. The question of whether to book lunch or dinner matters here, and it is worth thinking through before you reserve.
At most serious omakase counters globally, the lunch sitting offers the same kitchen and the same fish sourcing at a lower total cost, with a shorter course count or a compressed format. If Uni Omakase follows the pattern common to Michelin-recognized Japanese restaurants, the lunch experience is the stronger value argument: you access the same technical quality at reduced spend, in a room that tends to be quieter and less performative than the evening sitting. For a first visit, especially if you are calibrating whether the format suits you, lunch is usually the better entry point.
The dinner sitting at a venue like this carries a different set of expectations. The room's energy shifts, the occasion weight increases, and the full course sequence tends to run longer. If you are booking for a celebration, an anniversary, or a business dinner where the setting needs to signal effort and seriousness, the evening sitting earns its premium. Special occasions are where the $$$$ price point at dinner feels proportionate: you are paying for a controlled environment, precise sequencing, and a meal that takes the decision-making entirely off the table for two to three hours.
Both sittings benefit from the same caveat: this is a hard booking. With Michelin Plate recognition in consecutive years and a rating that puts it among the most-reviewed high-end venues in Buenos Aires, demand at Uni Omakase reliably outpaces availability. Plan for at least three to four weeks of lead time, and consider that the dinner sittings on weekends will be the first to fill.
Omakase counters are inherently intimate formats. The Guatemala Street address places Uni in the heart of Palermo's restaurant corridor, a neighborhood that runs loud and social on weekend evenings. Inside an omakase room, the dynamic is different: counter seating, a focused interaction with the kitchen, and a noise level that by design stays lower than the open dining rooms nearby. This is not a venue for a large group looking for an animated table. It is a venue for two to four people who want the meal itself to be the event.
For solo diners, the counter format is genuinely suited to the experience. A single seat at an omakase counter is never awkward in the way a table for one can be , you are facing the kitchen, engaged with the progression, and the format treats individual diners as the intended audience rather than an afterthought. Solo dining here is a reasonable choice, not a compromise.
If you are spending significant time in Buenos Aires and want to cover the full range of the city's serious dining, Uni Omakase anchors the Japanese end of the spectrum while venues like Aramburu and Trescha cover modern Argentinian tasting menus at comparable price points. Crizia is the contemporary alternative for a lighter seafood-focused evening without the omakase commitment. And Don Julio remains the reference point for what Buenos Aires does leading: wood-fired beef at the highest local standard.
Beyond the city, Argentina's serious dining extends well beyond Buenos Aires. Azafrán in Mendoza is the strongest restaurant argument for pairing a wine region trip with destination dining. Cavas Wine Lodge in Alto Agrelo covers the wine country accommodation and dining combination. For Patagonia, EOLO in El Calafate and Awasi Iguazu are the top-tier lodge dining options at opposite ends of the country. For a gaucho estancia experience, La Bamba de Areco in San Antonio de Areco is the reference. For more context on where to stay and what to drink, see our Buenos Aires hotels guide, our Buenos Aires bars guide, and our Buenos Aires wineries guide.
If you want to benchmark Uni Omakase against the global omakase standard, Myojaku in Tokyo and Azabu Kadowaki in Tokyo represent the format at its most refined. Uni is not competing directly with Tokyo's leading, nor does it need to , it is the most credentialed omakase option in its city and price tier, and on those terms the booking is justified.
Commit to the format before you book. Omakase means no menu choices , the kitchen decides the sequence, and at $$$$ pricing you are paying for that expertise. Uni holds Michelin Plate recognition in 2024 and 2025, which signals reliable technical standards. For a first visit, the lunch sitting is a better entry point: lower spend, quieter room, same kitchen. If you have eaten omakase before and are comfortable with the format, the dinner sitting delivers more occasion weight for celebrations.
Yes, and arguably better suited to solo dining than most $$$$ restaurants in Buenos Aires. Counter seating is the natural format for a single diner , you are positioned facing the kitchen, engaged with each course as it arrives, and the service interaction is direct. Venues like Don Julio can feel socially oriented for a solo visit; Uni Omakase does not carry that dynamic.
At minimum three to four weeks, and longer for weekend dinner sittings. Michelin Plate recognition in consecutive years has increased awareness internationally, which means the venue draws visitors as well as locals. If your travel dates are fixed, book as soon as your plans are confirmed , this is not a walk-in counter in practice, regardless of what the policy may technically allow.
No dress code is listed in the venue data, but the $$$$ price point and omakase format suggest smart casual at minimum. Treat it as you would a Michelin-recognized tasting menu restaurant: clean, considered, not formal but not casual either. Avoid athletic or beach wear. If you are coming from a day of sightseeing, plan for a change before your sitting.
Omakase counters by design are bar-adjacent , counter seating facing the kitchen is the standard setup for the format. Whether Uni offers a separate walk-in bar arrangement is not confirmed in the available data. Assume that all seating is reservation-based and tied to the omakase service. Do not arrive expecting a drop-in drink or a partial menu at the counter.
No specific policy is confirmed in the available data. Omakase is a format that is structurally challenging for dietary restrictions , the kitchen designs the sequence in advance, and fish and seafood are typically central to the progression. If you have serious restrictions, contact the venue directly before booking to confirm what accommodation is possible. Do not assume flexibility; clarify it early, and if the format cannot work around your needs, Aramburu or Trescha offer tasting menu formats with wider dietary accommodation at comparable price tiers.

Side-by-side comparison to help you decide where to book.
Commit to the format before you book. Omakase means no menu choices — the kitchen sets the sequence, the pace, and the portion count, and at $$$$ pricing you are paying for that expertise, not flexibility. Uni holds back-to-back Michelin Plate recognition (2024 and 2025), which signals consistent kitchen standards rather than a one-off performance. If you want to order à la carte Japanese in Buenos Aires, this is the wrong room.
Yes — counter-format omakase is arguably better suited to solo dining than most $$$$ restaurants in Buenos Aires. You face the kitchen, the pacing is set for you, and there is no awkward table dynamic to manage. At $$$$ per head, the solo cost is what it is, but you are getting the full experience without compromise. Compared to a place like Don Julio, where solo dining at a table can feel underserved, Uni's counter format works in your favour.
Three to four weeks minimum, and longer for weekend dinner sittings. Consecutive Michelin Plate recognition in 2024 and 2025 has expanded Uni's international profile, which tightens availability beyond the local Buenos Aires crowd. If your travel dates are fixed, book as soon as they are confirmed rather than waiting until you arrive in Palermo.
No dress code is listed in the venue data, but $$$$ pricing and a Michelin Plate counter format set a clear register. Treat it as you would any serious tasting-menu restaurant: put-together, not casual. There is no evidence of a jacket requirement, so smart casual is a reasonable floor — just avoid anything you would wear to a neighbourhood bistro.
Omakase by definition is counter dining — sitting at the pass facing the kitchen is the format, not a bar option alongside it. Whether Uni offers any walk-in counter seats or drop-in availability is not confirmed in the venue data, but given the booking lead times required, treating this as a reservation-only experience is the practical approach.
No specific policy is confirmed in the available data, and the omakase format itself makes this structurally difficult — the kitchen designs a fixed sequence, and substitutions can disrupt the whole progression. If you have serious dietary restrictions, contact Uni directly before booking rather than assuming accommodation is possible. At $$$$ pricing with a Michelin Plate, most counters at this level will make an effort, but confirmation in advance is the only way to know.
Keep this venue in your Pearl passport, rate it after you visit, and track it alongside every other place you collect.
