Set in a gorgeous house, complete with winding staircase and rooftop terrace, BA's place to see and be seen (and just simply have fun) is as attractive as the people that frequent it. The secret formula? Excellent music (a blues, soul, funk and rock mix that gets people dancing till the early morning); tasteful decor, including vintage radios and a collection of paintings; and easily the best caipiroskas in the city. On warmer nights, sip cocktails under the stars, but as the evening turns into morning, the living room downstairs is the place to be: the music gets louder, the crowd gets merrier, and the pretty people start dancing. Chef Fona also cooks up an excellent five-course dinner menu (call to reserve). Be prepared to queue at weekends.
