Restaurant in Buenos Aires, Argentina
Michelin-recognised value, no occasion required.
Ácido earned a Michelin Bib Gourmand in 2025 — a step up from its 2024 Michelin Plate — making it one of the clearest cases for contemporary Buenos Aires cooking at a $$ price point. Chef Tim Ziegler's restaurant on Charlone 999 is easy to book and delivers quality that exceeds what the price suggests. Go in person; this is not a takeout kitchen.
The most common mistake first-timers make with Ácido is approaching it like a special-occasion splurge. It is not. Chef Tim Ziegler's contemporary restaurant on Charlone 999 earned a Michelin Bib Gourmand in 2025 — an upgrade from its 2024 Michelin Plate , which means the guide's own assessors flagged it as a place delivering cooking above its price point. At a $$ price range, you are getting Michelin-recognised quality without the $$$ or $$$$ bill. That is the booking case in one sentence.
If you are visiting Buenos Aires for the first time and trying to work out where contemporary Argentine cooking sits outside the steakhouse circuit, Ácido is one of the clearest answers at this price tier. It is not a grand dining room and it does not try to be. The address , a corner in a quieter residential stretch of the city , tells you something about the register before you walk in. This is neighbourhood-restaurant ambition operating at a level the neighbourhood does not always expect.
Ácido sits in the contemporary cuisine category, which in Buenos Aires typically means a kitchen working with local produce and technique that draws on international influences without abandoning Argentine identity. Under Ziegler, the cooking has drawn enough critical attention to move from a Michelin Plate to a Bib Gourmand in a single cycle , a meaningful jump that suggests the kitchen is not standing still.
With 535 Google reviews averaging 4.1, the crowd verdict is positive but not unanimous. A 4.1 is respectable rather than rapturous, which usually points to a room where the cooking outperforms the service or the space rather than everything firing at the same level. For a first visit, that means: go for what's on the plate, not the full hospitality package.
On the sensory front, contemporary kitchens at this price point in Buenos Aires tend to run open or semi-open, and the aromas that reach the dining room , reduction-heavy sauces, char from the grill, herb-forward finishing , are often part of the experience. Without verified specifics on Ácido's kitchen layout, do not plan around that, but be prepared for a room where the cooking is present in the air as well as on the table.
Given the Bib Gourmand recognition, some diners will want to know whether Ácido is worth ordering in. The honest answer: contemporary plated cuisine at this level almost never travels as well as it eats in the room. The category , precise, technique-led, with composed plating , is exactly the kind of cooking that loses something in a delivery container. The sauces separate, the textures shift, and the temperature window for the dish as intended is tight. If you are in Buenos Aires and can get to Charlone 999, eat there. Reserve delivery for the nights you genuinely cannot.
That said, if you are staying somewhere in the city and the question is whether a takeout order from Ácido beats other $$-tier delivery options in the same neighbourhood, the Michelin credentialing at least guarantees the underlying quality of the ingredients and preparation. It will still be better than most. It just will not be the same dish the kitchen intended you to eat.
For context on the wider Buenos Aires contemporary dining scene, Anafe and 4ta Pared are both worth comparing if you are building a shortlist of in-room contemporary options at a similar price tier. Crizia moves into slightly different territory but operates in the same neighbourhood conversation.
Booking difficulty is rated Easy. Given the Bib Gourmand status, that is a green light to plan this as part of a Buenos Aires itinerary without stress , but Michelin recognition does accelerate walk-in difficulty, so a reservation in advance is still the sensible move. Hours and a direct booking method are not confirmed in current data; check Google or the address directly for current operating information.
The address is Charlone 999 in Buenos Aires. Getting there from central neighbourhoods is direct by taxi or ride-share. The $$ price range means this will not be the most expensive dinner of a Buenos Aires trip , budget accordingly and do not over-engineer the evening around it.
For broader trip planning in the city, our full Buenos Aires restaurants guide covers the category in depth. If you are moving beyond the capital, Azafrán in Mendoza and Cavas Wine Lodge in Alto Agrelo are worth building around. For other contemporary benchmarks internationally, César in New York City and Jungsik in Seoul operate in the same broad genre at different price points.
If you are building a longer Buenos Aires itinerary around food, A Fuego Fuerte and Alcanfor are two other addresses worth slotting in alongside Ácido. For the full picture beyond restaurants, see our Buenos Aires hotels guide, our bars guide, and our experiences guide. If you are travelling beyond the city, Awasi Iguazu in Puerto Iguazu, EOLO in El Calafate, La Bamba de Areco, and El Colibri in Santa Catalina are Pearl-tracked options worth considering. Our Buenos Aires wineries guide rounds out the picture if wine is part of the trip.

Booking difficulty at Ácido is rated Easy, meaning you do not need to plan weeks in advance the way you would for a $$$$ Michelin-starred room. A few days ahead is generally sufficient, though the Bib Gourmand recognition in 2025 will draw more attention than the venue had in previous years. If you have a specific evening in mind during peak Buenos Aires dining season (spring and early summer, October to December), book a week out to be safe. Walk-ins may be possible on quieter weeknights but are not guaranteed.
Specific seating configurations at Ácido are not confirmed in current data. In Buenos Aires contemporary restaurants at the $$ tier, bar or counter seating is common but not universal. Contact the venue directly before your visit if bar dining is your preference , it is worth asking, particularly for solo diners or pairs who want a more informal format.
Yes, at the $$ price range and with Easy booking difficulty, Ácido is a low-friction solo dining option. Contemporary restaurants at this tier in Buenos Aires tend to have a mix of small tables and counter options that suit solo diners without making it feel awkward. The Michelin Bib Gourmand credential means the cooking justifies the trip on its own merits. If you are a solo diner looking for comparison, Anafe is another Buenos Aires contemporary address worth considering at a similar price point.
No dress code is confirmed for Ácido. At the $$ price tier in a residential Buenos Aires neighbourhood, smart casual is the safe assumption , think the kind of outfit you would wear to a good neighbourhood bistro rather than a formal dining room. The Bib Gourmand designation signals quality cooking in an accessible setting, not white-tablecloth formality. Avoid beachwear or overly casual dress out of respect for the kitchen's ambition, but a jacket is not expected.

A quick look at how Ácido measures up.
Booking is rated Easy, so a few days' notice is typically sufficient rather than weeks out. That said, Ácido's 2025 Michelin Bib Gourmand recognition will draw more attention, so booking 5–7 days ahead is a sensible buffer, especially on weekends. It is not the kind of reservation that requires the same forward planning as Aramburu or Don Julio.
Bar seating availability is not confirmed in the venue record, so treat that as an open question when you book or arrive. What is clear is that Ácido's Easy booking difficulty means you are unlikely to need bar seating as a fallback — securing a table at this $$ Bib Gourmand is not the obstacle it would be at a harder-to-book address.
Yes, and arguably the best format for it among Buenos Aires Michelin-recognised restaurants at this price point. Contemporary tasting-style kitchens at $$ pricing with Easy booking difficulty are low-friction for solo travellers. The residential Charlone 999 address also means a quieter room than central Buenos Aires spots, which suits solo diners who want to focus on the food.
The venue data does not specify a dress code, and at $$ pricing with a Bib Gourmand designation — rather than a full Michelin star — a relaxed, put-together look is appropriate. Think neat casual rather than formal. Ácido is a neighbourhood contemporary restaurant, not a white-tablecloth occasion venue.
Keep this venue in your Pearl passport, rate it after you visit, and track it alongside every other place you collect.
