Antares
Founded in the city of Mar del Plata in 1999, this is now a successful national brewer making dozens of brews. The spacious bar attracts a cosmopolitan group of drinkers who keep it packed from after-office until the wee hours. Service is friendly and efficient, the music is feel-good, and the bar snacks are tasty. In San Telmo? Check out the outpost inside the Mercado de San Telmo.
