Buenos Aires

The currency is the Argentine peso (ARS), around 1,530 to the dollar at the official rate in September 2026. The rate moves week to week and inflation, though falling since 2024, is still high, so treat any peso price as an estimate and do the math in dollars. The gap between the official and parallel rates, which for years forced tourists to bring cash dollars, has practically closed. Paying with a foreign card now usually gets you a rate equivalent to the market's, and cards are accepted at almost every restaurant, hotel and shop. Non-resident foreigners get an automatic refund of the 21% VAT on lodging when they pay with a card issued abroad or in foreign currency. Reference ranges: café con leche and medialunas US$4–6; lunch at a bodegón US$10–15; parrilla dinner with wine US$20–35; 5 km taxi ride about US$6; midrange hotel US$70–120 a night. Carry some cash for street fairs, kiosks, taxis and tips, because ATMs charge a high fee per withdrawal and cap the amount per transaction. The restaurant tip is about 10%, almost always in cash and separate from the bill. Many places also charge a cubierto per person, which is the bread and table service charged before you decide whether you want the bread.

Ezeiza sits 35 km away, with a flat taxi fare

Ezeiza (EZE), 35 km south of the center, handles almost all international flights. A fixed-fare taxi or remis costs about US$35–45 and takes 45–70 min depending on traffic, and the Tienda León bus runs to Retiro and Puerto Madero about every 30 min, for about US$12–15. Aeroparque Jorge Newbery (AEP), for domestic and regional flights, is inside the city, on the riverfront, 15–25 min from Palermo or the Microcentro (about US$8–12 by taxi). Check your ticket for which of the two your flight leaves from, because they're 35 km apart. Uber, Cabify and DiDi work at both airports, but the pickup point moves often: check in the app where it is before leaving the terminal. Arriving from Uruguay, the ferry docks in Puerto Madero, a 15-min walk from Plaza de Mayo.

Everything runs through the SUBE card

Everything runs on the SUBE card, sold at kiosks and subte ticket windows and reloadable at any kiosk with the sticker: register the card online, because the unregistered fare is much higher. In September 2026 a subte ride with a registered SUBE costs ARS 1,753 (about US$1.15) versus ARS 2,541 unregistered. The colectivo starts at ARS 888 for trips of up to 3 km, with a progressive discount after 20 rides in a month. The subte also accepts contactless bank cards (check at the gate). The subte has six lines (A, B, C, D, E and H), closes around 10:30pm and only opens at 8am on Sundays, so it won't get you home from dinner or the milonga. The colectivos, about 180 lines, run 24 hours and cover the rest. Check the line's branch in the app before boarding, because many lines have different branches under the same number. The grid of 100 m blocks makes the city flat and walkable (10 blocks = 1 km), there are Ecobici public bikes at more than 300 stations, and the black-and-yellow taxis stop on the street. At night, a ride-hailing app is the most predictable option.

Violent crime in Buenos Aires is low for a South American capital. The real risk is theft and snatching of phones and bags, concentrated in the Microcentro on weekdays, on Calle Florida, at the Retiro and Constitución stations and around them, in Once and around La Boca outside the tourist strip. Keep your phone put away, don't wear a backpack on your back on a crowded bus and never hang your bag on the chair at a sidewalk table. In taxis there's the “cambiazo” scam, where the bill you hand over is swapped for a fake one right in front of you: say out loud the amount and denomination you're handing over, or pay through the app. Avoid the area around Villa 31, behind Retiro, and the Microcentro streets after 9pm, when the area empties out. Protests are frequent and predictable, especially on Wednesdays at Plaza de Mayo and in front of Congress. They're usually peaceful, but they close avenues and reroute bus lines, so check before heading out. Tap water is safe to drink in the city.

Greet people with a kiss on the cheek

A kiss on the right cheek, touching faces, between any combination of people: even two men who just met. Offering a hand instead works, but pulling back without explanation reads as coldness.

Eat dinner after 9pm, on porteño time

Porteños sit down to dinner after 9pm, and dining rooms fill up around 10pm. Arriving at 7pm means eating alone in an empty restaurant, or being told the kitchen isn't serving yet.

You ask for the bill

The waiter won't bring the bill before you ask, because occupying the table is part of what you paid for. Say “la cuenta, por favor” or make the writing-in-the-air gesture; waiting for it can cost you another hour at the table.

Don't ask for the mate

Mate circulates among acquaintances, always served by the same cebador in the same order. Asking a stranger in the park for a sip is like asking to borrow their toothbrush. If offered, accept, drink it all down to the straw's gurgle, and hand it back without thanking: saying “gracias” means you don't want more.

The wrong team jersey matters in the wrong neighborhood

In La Boca, near La Bombonera, and in Núñez, near River's Monumental, a rival team's shirt provokes home fans any day of the week, not just on match day. To walk around these neighborhoods, leave your soccer shirt at the hotel.

The Falklands aren't table talk

The 1982 war and the islands' sovereignty are serious topics across the whole political spectrum, never a joke. The same goes for soccer jabs between Argentina and Brazil when you don't know the people at the table.

Counting on the subte after dinner

Counting on the subte to get back from dinner. It closes around 10:30pm, when the night is just getting started; after that it's colectivo, taxi or app.

Changing money on Calle Florida

Looking for “cambio” on Calle Florida. The arbolitos still call out from the sidewalk, but the advantage of the parallel dollar has practically vanished since 2024, while the risk of counterfeit bills and doctored change remains the same.

Boarding a colectivo without SUBE

Boarding the colectivo without SUBE. You can't pay in cash anymore: without the card, bought and loaded at a kiosk, you simply don't get on the bus.

Treating La Boca as a walking neighborhood

Treating La Boca as a neighborhood to stroll through. The Caminito and Bombonera corridor is calm during business hours; three blocks further it stops being so, and at night you don't walk there.

Palermo to La Boca is ten kilometers

Underestimating the distances. It's 203 km² and the grid is deceptive: Palermo to La Boca is about 10 km and nearly an hour in late-afternoon traffic.

¿Cuánto sale?

How much is it? In porteño speech, “salir” replaces “costar”

La cuenta, por favor

The bill, please: without asking, it doesn't come

Dale

Agreed / sure / let's go: probably the city's most-used word

Che, ¿me das una mano?

Hey, can you give me a hand? “che” is the neutral way to call someone

¿Tenés cambio?

Got change? Note the voseo: “tenés,” not “tienes”

Un cortado y dos medialunas

How you order the counter coffee, with a splash of milk, and two medialunas

The river's mud and the bluff

The city occupies 203 km² of pampas plain on the south bank of the Río de la Plata estuary, which is about 45 km wide there and mud-colored from sediment carried by the Paraná and Uruguay rivers. There's no relief: the only visible fold is the bluff, the old riverbank, which runs through Belgrano, Recoleta and San Telmo some 15-25 m above the water and determined where the city was built first.

The polluted Riachuelo and the buried waterways

To the south, the Riachuelo (Matanza-Riachuelo basin) marks the boundary with the province and is one of the continent's most polluted rivers, under a court-ordered cleanup plan since 2008; to the east, Puerto Madero and the Reserva Ecológica sit on landfill reclaimed from the river in the 1970s and 1980s. The streams that once crossed the city (Maldonado, Vega, Medrano) were piped underground in the early 20th century and now run beneath avenues like Juan B. Justo, which explains the fast flooding in heavy rain.

The grid and the street numbering

The urban fabric is the Spanish grid of 100 m blocks, cut after 1900 by diagonal avenues and by the 9 de Julio, about 140 m between facades; street numbers grow from the river and from Avenida Rivadavia, which divides north from south, so a four-digit address already tells you the approximate distance in hundreds of meters.

Tango came out of the outskirts

Tango was born in the port outskirts at the end of the 19th century, blending Cuban habanera, Afro-Rioplatense candombe and rural milonga. Carlos Gardel fixed the song form in the 1920s and 1930s, and Astor Piazzolla broke with the dance floor starting in the 1960s. UNESCO recognized tango as intangible heritage in 2009, in a joint bid with Montevideo. Today two parallel scenes exist: the tourist dinner show (US$80-150) and the milonga, the real dance in halls like Salón Canning, La Catedral and La Viruta, with a beginners' class beforehand and its own codes. The invitation is made with a look, the cabeceo, and refusal is simply not looking back.

Bookstores, independent theater and film

Buenos Aires has one of the highest bookshop densities in the world (estimates around 700 in the municipality), and the International Book Fair, at La Rural, draws over 1 million visitors in three weeks. Borges ran the National Library from 1955 to 1973; Cortázar, Sabato, Silvina Ocampo, and Ricardo Piglia wrote the city street by street. Avenida Corrientes is home to commercial theater, and the city supports about 300 independent venues, many with 40 seats and a weekend season. In film, four movies capture the country's spirit: Nine Queens (2000), The Secret in Their Eyes (the Oscar for Best Foreign Language Film in 2010), Wild Tales (2014), and Argentina, 1985 (2022).

Soccer, rock nacional and psychoanalysis

Soccer sits at the center of city life: when Boca and River play the superclásico, all of Buenos Aires stops, and the stadiums are a single color, because away fans have been banned from the Argentine league since 2013. Outside the stadium, rock nacional has kept its own circuit for five decades, from Charly García and Luis Alberto Spinetta to Soda Stereo, with venues in Chacarita, Almagro and Villa Crespo. Psychoanalysis has an address too: the city has one of the highest rates of psychologists per capita in the world (about 200 per 100,000), the blocks of Palermo around Plaza Güemes have been called Villa Freud since the 1970s, and talking about your analyst at dinner is ordinary conversation.

On Heroes and Tombs, Ernesto Sabato (1961)

A novel that uses the city's real topography (Parque Lezama, Barracas, the imagined tunnels beneath downtown) to explain porteño melancholy and the fracture between north and south.

Nine Queens, Fabián Bielinsky (2000)

A heist film shot in the Microcentro and Puerto Madero on the eve of the 2001 crisis. The city appears as a system of small, chained cons, which is how porteños themselves tell that period.

Tango: Zero Hour, Astor Piazzolla (1986)

Tango after it left the dance hall: bandoneón, double bass and dissonance. It's the fastest way in to understand what the city did to its own music, and why the argument over it lasted thirty years.
