For $10, today's side deal gets you admission and one drink ticket to the always-lively S.O.B.'s (Sounds of Brazil) in the colorful gray area between SoHo and the West Village. Admission is normally $15 for the after-10 p.m. crowd, and drinks such as the establishment's famous mojito or caipirinha are priced $6–$13, giving this deal a total value of up to $28 (the lower-priced non-alcoholic beverages are eligible as well). Redeem you Groupon between 10 p.m. and midnight on any Saturday over the next two months.

Every Saturday, S.O.B.'s erupts into a huge, Carnivàle-esque dance party. A live set from bands teleported straight from Brazil plays a raucous set accompanied by fully decked-out Rio dancers. Check out the schedule for upcoming Saturday-night acts. As the night's intensity rises, a live marching band will materialize seemingly and definitely out of thin air to bring the party to levels unseen since the last furiously dancing dodo bird returned to its home planet. The unmatched atmosphere creates the ideal backdrop for a bachelorette, birthday, or anniversary celebration or just to change up the pace of a standard Saturday night from steady to mind-blowing.

Reviews

The New York Times and the Village Voice just want to dance, while New York magazine lists S.O.B.'s as a Critic's Pick:

• For a mixed crowd of all ages and all dance abilities, there’s Saturday’s Samba Soul at S.O.B.’s, after 26 years the city’s longest-running Brazilian night. Bands range from samba to forró to Bahian rhythms like axé, but often fall somewhere in between or somewhere else completely. On a recent night, the group Ogans played its percussion-heavy Bahian beats and stuck in the Brazilian version of Bob Marley’s “No Woman No Cry,” before ceding to some dazzling capoeira dancers. – Seth Kugel, New York Times
• SOB's (Sounds of Brazil) opened in 1982 and has proven a blessing to the city's lovers of salsa, samba, reggae, Latin alternative, hip-hop, and more. The attractive space offers weekly parties with DJs and regular shows featuring some of the best musical acts and turntablists from varying countries, as well as locals and other Stateside musicians. The dance floor isn't of immense proportions but makes up for it in intensity. The empañadas and Brazilian pastries are top-shelf, as are the caiprihinas and mojitos. – Village Voice
• A genuinely mixed crowd of revelers flocks to S.O.B.'s for polyrhythmic, south-of-the-equator beats: Cuban salsa, Jamaican reggae, Brazilian samba, African pop, even Indian Bhangra (laced with break beats) at DJ Rekha's red-hot Basement Bhangra party. Many prominent touring hip-hop acts also stop by. Fruity drinks, naturally, fuel the all-night bop; try their flavorful mojito or caipirinhas – Peter Landau, New York

Citysearchers give S.O.B.'s 4.5 stars, and Yelpers give it four:

• That was one of the most fun nights that I have ever been a part of in NYC EVER! – Maddiesmom, Citysearch
