Taxis in Buenos Aires
Subways close down around 11 p.m., so after dinner you’ll need to hail a cab. A glowing red “LIBRE” sign on the windshield means a cab is available; many locals will take cabs only with “Radio Taxi” signs on the roof, as they’re thought of as safer. Cabs charge about $3.80 to get in and 38 cents per 200 meters. A crosstown ride shouldn’t cost more than $12.
