What began as a recreation area for immigrants from Brazil’s northeast is now a destination for visitors looking to get off the beaten tourist path. The densely populated São Cristóvão quarter is home to this enormous complex, open seven days a week, to which visitors may arrive at a reasonable hour and not get out before dawn. Afternoons are for shopping and noshing; but after dark, the volume goes up, and the marketplace becomes a scene for partying, pop-up karaokes, and live-music performances that are 100-proof Brazil. Authentic northeastern music known as forró plays until sunup.
