Argentina is frequently referred to as one of the most LGBT-friendly Latin American countries. There is a visible LGBT scene in Buenos Aires, the capital, with many gay bars, nightclubs, cafés, restaurants and other venues and events. Nicknamed "Latin America's gay capital", Buenos Aires has become an important recipient of LGBT tourism. Due to same-sex marriage bans there, many couples from neighbouring Chile and Paraguay come to Buenos Aires to marry, as Argentina does not have any residency requirements for marriage. Outside Buenos Aires, there are visible LGBT scenes in Córdoba, Rosario, Mendoza, Puerto Madryn, Ushuaia, and Mar del Plata.
