In a cozy corner of Lapa, Rio’s historic and prominent nightlife district, Beco do Rato is the place for down-to-earth samba, good music, beautiful people, cold beer, and delicious Brazilian finger food. Its no-fuss approach to dining and dancing makes it a favorite with the local community. Fridays are best for national specialties: samba and black bean stew. Be sure to remember to bring some comfortable shoes and a very big appetite: There’s little chance you’ll make it out of here without wanting to join in the fun!
