Taxis
You can easily spot a ‘Radio Taxi’ – they are black and yellow in the Capital, and white with blue lettering in the Provinces. They are the safest option for taxi service, especially in the capital. Airport taxis in Buenos Aires are white and blue.
There are few problems with taking taxis in Argentina. Just be sure to have small bills to pay the driver.
Local privately-owned taxis called Remises (hired car and driver) are a very convenient and low-priced way to get around (or get your groceries home from the almacén (warehouse or grocery store). You need to either call the dispatcher or walk to the street-front office with a “Remise” sign in the window nearest you. You cannot flag them down on the street.
