Museo de Arte Latinoamericano de Buenos Aires (MALBA)
Best museum and art gallery in Buenos Aires? Best cultural venue period is my uncontroversial assessment. The permanent collection is a Who’s Who of Latin American art history, with innovators of the caliber of Frida Kahlo, Diego Rivera and Tarsila do Amaral all represented. Temporary shows please the crowds—even the ones that aren’t obvious crowd pleasers. Be sure to exit through the hip gift shop.
