Yes. Buenos Aires is Argentina's most card-friendly city, but cash (especially USD) is still central to how the city works. The blue dollar parallel exchange rate means bringing USD bills and exchanging them at cuevas or on Calle Florida gets you 15–30% more pesos than using an ATM or paying by card. Many visitors pay for hotels and restaurants by card but exchange dollars for everything else.
Where You Will Need Cash
San Telmo Sunday market (almost entirely cash). Taxis (metered, cash-only). SUBE card top-ups for metro and buses (cash at kiosks). La Boca / Caminito vendors. Milongas (tango halls, many cash at the door). Tips at restaurants (always in cash, even when paying the bill by card). Small neighborhood shops and cafes outside Palermo and Recoleta.
Where Cards Work Fine
Restaurants and bars in Palermo, Recoleta, Puerto Madero, and Belgrano. Hotels. Shopping malls (Alto Palermo, Galerias Pacifico). Uber and Cabify (card through the app). Supermarkets. Note: card payments use the official exchange rate, which is worse than the blue dollar rate. For the best value, exchange USD cash at cuevas and spend pesos.
Paying by Card in Buenos Aires
Card acceptance swings wildly depending on which barrio you are in. Visa and Mastercard dominate. Amex is hit-or-miss outside hotels. Discover is not useful here.
Palermo (Soho & Hollywood)
The most card-friendly neighborhood. Nearly every restaurant, bar, boutique, and café takes Visa/Mastercard with contactless. Apple Pay and Google Pay work at most modern terminals. Some craft cocktail bars and wine bars add a 5–10% recargo (surcharge) for card payments. Ask "hay recargo con tarjeta?" before ordering.
Recoleta
Upscale restaurants, hotels, and shops accept cards reliably. Recoleta Mall and surrounding boutiques have modern terminals. Traditional parrillas on side streets take cards but appreciate cash tips. The weekend artisan fair near the Recoleta Cemetery is cash-only.
Puerto Madero
The most modern district and the one area where you could realistically go card-only for an entire day. Every waterfront restaurant and hotel accepts contactless. Prices here are the highest in the city, aimed at tourists and business travelers.
San Telmo
Established restaurants and bars on Defensa Street accept cards. The famous Sunday Feria de San Telmo is almost entirely cash-only: antique vendors, street food, tango buskers, all pesos. Milongas (tango halls) vary, but many prefer cash at the door. Come with pesos on Sundays.
Microcentro / Florida Street
Fast food chains and department stores accept cards. Smaller lunch spots serving the office crowd are often cash-only or cash-preferred. Galerías Pacífico (the upscale mall at Florida & Córdoba) is fully card-friendly. This is also the area where most dollar exchange happens, so you will have pesos on hand.
La Boca
Tourist restaurants along Caminito accept cards, but the surrounding neighborhood is cash-only. Do not wander beyond Caminito as the surrounding blocks are unsafe for tourists. Keep cash amounts small and leave valuables at your hotel.
Belgrano
A residential neighborhood with solid card acceptance at restaurants and Chinatown shops along Arribeños Street. The Belgrano C area near Barrancas park has modern cafes with contactless. Less touristy than Palermo, so prices are lower for comparable food quality.
Villa Crespo
An up-and-coming foodie neighborhood. New restaurants and natural wine bars accept cards, but older shops and the outlet clothing stores along Aguirre Street are often cash-only or add a surcharge. Worth exploring for lower prices and fewer tourists than neighboring Palermo Soho.
Where to Exchange Dollars in Buenos Aires
For background on the blue dollar rate, which bills to bring, and how street exchange works, see the Argentina guide. Below are the specific locations and methods you will use once you are in the city.
Cuevas Near Florida Street
Cuevas are informal exchange offices, typically on upper floors of office buildings within a few blocks of Calle Florida. They offer the best rates, usually 1–3% above what street changers offer. Ask your hotel, hostel, or Airbnb host for a referral. The process is businesslike: you buzz in, take an elevator up, sit down at a desk, agree on a rate, exchange, and leave. Expect to exchange $200+ at a time.
Calle Florida (Between Av. de Mayo and Plaza San Martín)
The pedestrian stretch where arbolitos call "cambio, cambio." Rates are slightly below cuevas but the process is faster and requires no appointment. Busiest (and most competitive rates) midday on weekdays. Thinner crowds on weekends and evenings.
Western Union Self-Transfer
A growing number of travelers send themselves money via Western Union before arriving. You initiate the transfer through the app using your debit card, selecting Buenos Aires as the pickup location and ARS as the payout currency. WU applies a rate close to the blue dollar. You pick up pesos at any WU branch (dozens across the city). No street interaction required. Check the WU app rate against dolarito.ar to see if it is competitive on the day you transfer.
⚠ Skip the Official Casas de Cambio
Licensed exchange houses near airports and in tourist areas use the official rate. When the blue/official gap is wide, that means 15–30% less pesos for your dollar. The only time these are worth considering is if the gap has narrowed below 5%. Check dolarito.ar before your trip.
ATMs in Buenos Aires
For details on withdrawal limits and which banks are best for foreign cards, see the Argentina guide. This section focuses on where to find machines in Buenos Aires and how to stay safe using them.
Look for these logos on the street. These banks work best with foreign cards.
Banco Galicia
Santander
BBVA
Banco Nación
During Banking Hours
Banco Galicia branches are the top pick for foreign cards. Clusters on Av. Santa Fe (Recoleta/Palermo border), Av. Corrientes (Microcentro), and Av. Cabildo (Belgrano). Santander has branches near Plaza Italia and along Av. Santa Fe that are convenient if you are staying in Palermo. BBVA at Av. Callao and Av. Corrientes is centrally located. Always use ATMs inside the bank lobby, not the street-facing vestibule.
After Hours: Shopping Mall ATMs
When bank branches are closed, mall ATMs are your safest option. All have bank-operated machines inside:
Alto Palermo (Av. Santa Fe 3253, Palermo). Galerías Pacífico (Florida & Av. Córdoba, Microcentro). Patio Bullrich (Av. del Libertador 750, Recoleta). Dot Baires Shopping (Vedia 3626, Saavedra). Malls are open until 9–10 PM daily, including weekends.
⚠ Avoid Standalone Machines
Independent ATMs near La Boca, the San Telmo market entrance, and along Florida Street charge higher fees and have been linked to card skimming. If an ATM is not inside a bank branch or shopping mall, skip it.
Paying for Transport in Buenos Aires
The SUBE Card
The SUBE card is mandatory for all Buenos Aires public transport: colectivos (buses), the subte (metro), and commuter trains to places like Tigre. Buy one at any kiosko or subway station for a small fee. Load it with pesos at subway station machines, Rapipago/Pagofácil locations, or some kioskos. Loading is a cash transaction, so make sure you have pesos before trying to top up. A single subte ride costs around AR$100–200, making public transport extremely cheap for foreign visitors.
Taxis: Street vs. App
Black-and-yellow street taxis use a meter and accept cash only. Always confirm the driver starts the meter ("baje la bandera, por favor"). Have small bills ready, as drivers often claim they cannot break large notes. Uber works in Buenos Aires but operates in a legal gray area: drivers may ask you to sit in front and may cancel if the pickup location looks like a hotel doorman might see them. Cabify is the locally preferred alternative and operates openly. Both Uber and Cabify charge your credit card through the app, so no cash needed.
Airport Transfers
From Ezeiza (EZE), 35 km south of the city: Tienda León airport buses accept credit cards and run to the city center for a fraction of a taxi fare. Official remise (private car) counters in the arrivals hall also accept credit cards. If you take a metered taxi, you will need pesos. Do not exchange large amounts at the airport Banco Piano counter, as it uses the official rate.
From Aeroparque (AEP), on the city's riverfront: much closer, so a Cabify or Uber to Palermo or Recoleta costs very little through the app. The surrounding Palermo neighborhood has bank branches a short ride away if you need an ATM.
Tipping in Buenos Aires
The Argentina guide covers general tipping norms. Here are the Buenos Aires specifics that trip people up.
Things That Catch Visitors Off Guard
The cubierto (AR$1,000–3,000 per person) on your restaurant bill is a bread and table cover charge. It is not a tip, and it is not optional. Your 10% tip goes on top of that, in cash on the table, even if you pay the bill by card.
At parrillas, the waiter often brings the meat to your table on a small grill and serves you. Tip 10% as usual. At closed-door restaurants (puertas cerradas, a Buenos Aires specialty), tip is sometimes included. Check before adding more.
For delivery apps (Rappi, PedidosYa), tip through the app. Riders depend on it. For Uber and Cabify, tipping is not expected but you can add one through the app.
Baristas and counter service: leave coins in the tip jar or round up. Nobody expects 10% at a coffee counter. Hotel housekeeping: the equivalent of $1–2 USD per night in pesos, left on the pillow or nightstand.
Prices in Buenos Aires
Buenos Aires is extremely affordable for visitors with strong currencies. Prices change frequently due to inflation. USD equivalents below use the blue dollar rate.
| Item | Price (ARS) | Price (USD) |
|---|---|---|
| Subte (metro) ride | AR$100–200 | $0.10–0.20 |
| Medialuna (croissant) | AR$500–1,000 | $0.50–1 |
| Café con leche | AR$2,000–4,000 | $2–4 |
| Pizza slice (Corrientes Ave) | AR$2,000–3,000 | $2–3 |
| Milonga entry | AR$3,000–5,000 | $3–5 |
| Uber / Cabify across center | AR$3,000–8,000 | $3–8 |
| Happy hour cocktail (Palermo) | AR$4,000–6,000 | $4–6 |
| Malbec bottle (vinoteca) | AR$4,000–8,000 | $4–8 |
| Tenedor libre (all-you-can-eat) | AR$10,000–18,000 | $10–18 |
| Steak dinner at a parrilla | AR$15,000–25,000 | $15–25 |
| Football at La Bombonera | AR$15,000–30,000 | $15–30 |
| Tango show with dinner | AR$30,000–60,000 | $30–60 |
USD estimates at blue dollar rate (approximately AR$1,000 = $1). Rates shift frequently. Card payments use the official rate, which gives fewer pesos per dollar.
Day Trips from Buenos Aires
Colonia del Sacramento, Uruguay
The popular ferry day trip crosses into a different country with a different currency: Uruguayan Pesos (UYU). Do not bring Argentine pesos to spend there. Buquebus and Colonia Express ferry tickets can be purchased online with a credit card. In Colonia, most sit-down restaurants accept cards and ATMs dispense UYU. Uruguay has no parallel exchange market, so rates are straightforward. Bring some USD as backup for smaller shops.
Tigre Delta
Reachable by commuter train from Retiro station using your SUBE card (about 50 minutes, very cheap). The Tigre town center near the station has ATMs, restaurants with card terminals, and the Puerto de Frutos market (mostly cash). Once you board a lancha (boat taxi) into the delta, everything is cash: boat fares, island restaurants, riverside kiosks. Bring enough pesos for the day before leaving the Tigre town center.
San Isidro & Olivos
The northern suburban towns along the Tren de la Costa are more residential and less touristy. Card acceptance at restaurants is similar to Belgrano (mostly fine at sit-down places, less reliable at small shops). The Tren de la Costa requires a separate ticket paid in cash or with a contactless card at the station, not your SUBE.

Frequently Asked Questions
Do I need a SUBE card for Buenos Aires public transport?
Yes. The SUBE card is mandatory for all colectivos (buses), the subte (metro), and commuter trains. Buy one at any kiosko or subway station for a small fee. You load it with pesos at subway station machines, Rapipago/Pagofácil locations, or some kioskos. Loading is a cash transaction, so have pesos ready. A single subte ride costs around AR$100–200.
Is the San Telmo Sunday market cash only?
Almost entirely. Street vendors, antique sellers, and food stalls at the Feria de San Telmo only take cash. A few established shops along Defensa Street with permanent storefronts accept cards, but for the market itself you need pesos. ATMs near the market get long lines on Sundays, so withdraw or exchange beforehand.
Can I use Uber in Buenos Aires?
Yes. Uber operates in Buenos Aires but in a legal gray area, so drivers may ask you to sit in the front seat. Your foreign credit card works through the app. Cabify is the locally preferred alternative with the same card-through-app model. Both are cheaper than metered street taxis and eliminate the need for cash.
Can I use Apple Pay or Google Pay in Buenos Aires?
Contactless payments work at most modern terminals in Palermo, Recoleta, Puerto Madero, and Belgrano. Chain cafés like Havanna and Café Martínez accept them reliably. Smaller neighborhood shops, traditional parrillas, and businesses outside northern barrios often still require chip-and-PIN or cash.
What currency do I need for a day trip to Colonia del Sacramento?
Colonia uses Uruguayan Pesos (UYU), not Argentine Pesos. Do not bring ARS to spend there. Most restaurants in Colonia accept cards, and ATMs dispense UYU. Ferry tickets from Buquebus and Colonia Express can be purchased online with a credit card. Uruguay has no parallel exchange market, so rates are straightforward. Bring some USD as backup for smaller shops.
Where can I find an ATM late at night in Buenos Aires?
Shopping malls have bank ATMs inside and stay open until 9–10 PM. Alto Palermo (Av. Santa Fe 3253), Galerías Pacífico (Florida & Córdoba), and Dot Baires Shopping (Vedia 3626) are reliable options. After mall hours, some 24-hour gas stations have ATMs, but stick to well-lit, staffed locations. Avoid standalone street-facing machines after dark.
How do card surcharges work at Buenos Aires restaurants?
Some restaurants and bars in Palermo and San Telmo add a 5–10% recargo (surcharge) for card payments. This is separate from the cubierto (bread and table charge of AR$1,000–3,000 per person). The surcharge is not always listed on the menu, so ask "hay recargo con tarjeta?" before ordering if it matters to your budget.
