This resto-bar's interior is all sumptuous brown leather, armchairs and floor-to-ceiling mirrors: think sultry 1940s saloon updated for the young and chic. At the bar the menu is, for the most part, adventurous but sophisticated, and twists on classic cocktails include the Cherry Collins and a Tangerine Mary. Top DJs make RíoCafé the place to be at night from Wednesday to Sunday, when BA's beautiful like to hang out in the leafy patio. Food-wise, fragrant is the word, and fish and seafood are refreshingly well represented. Duck breast is served in a divine tamarind sauce, and the sea bass with vegetable curry, heavy on the ginger, is a real treat for tastebuds dulled by too much red meat. Throw in a Sunday brunch to rival New York's best and you have one of BA's hottest spots.
