If you're looking for a night out, Rua das Pedras is the place to crawl. This 1,219m-long (4,000-ft.) street has pubs, bars, discos, and restaurants open on weekends until 5am.
To simply sit, sip a drink, and check out the action, the place to be is the Anexo Bar and Lounge, overlooking the happening waterfront. If you prefer your entertainment live, there's Patio Havana, which features a nightly selection of jazz, blues, and MPB. Thursdays is salsa night. Should you get bored of the band, you can wander out to the ocean-side patio and enjoy the nighttime view. For a late night snack, locals and visitors gather at Chez Michou's large outdoor patio for a crepe (open until 6am in high season). Popular Rio brewpub Devassa has set up shop in Porto da Barra. To dance until you drop, Búzios boasts two mega-nightclubs on the Orla Bardot, Privilege and Pacha (one of Ibiza's hottest clubs). These only operate on Saturdays, with additional nights in high season. But remember, don't bother showing up until 1 or 2am.
