Champanharia Ovelha Negra, Rio de Janeiro

Fans of champagne and other sparkling wines should head straight for this Botafogo bar and restaurant, which offers a wide range of cavas, proseccos and—of course—champagnes. You'll need to have deep pockets if you want to sip the real thing, but the national bubblies are more than affordable. The wines, many of which are available by the glass, go well with the light dishes served here, such as the unusual yet delicious sandwich of Parma ham, Canadian sausage, brie and apricot. The bar is a favorite post-work pit stop for Botafogo office workers, which makes for a lively atmosphere and explains the weekday-only opening hours. - Lucy Bryson
