Your snobby South Beach acquaintances and trendy downtown hipster friends might scoff, but were here to tell you theres a neighborhood scene thats been simmering to a boil in a long-forgotten corner. South Miami has become what Coconut Grove used to be and what Coral Gables wishes it were a vibrant, densely populated epicenter of great restaurants, bustling bars, pseudo-clubs, and a strip joint just for good measure. For an indication of just how on and poppin South Miami is nowadays, cruise by RA Sushi Bar on a Friday night. Its like a block party of hot UM students, coupled-up thirtysomethings, and the Pinecrest cougar klatch, all jockeying for sidewalk space and sipping luscious-looking cocktails. RA is all about delicious sushi and knockout drinks. Take, for example, their seasonal offering the nog-asaki martini. Yummy. And now we can afford to indulge in a little RA even on our meager journalist wages, thanks to the joints revamped six-day happy hour. That means extended hours, lower prices, and food and drink specials from 3 to 7 p.m. On a Saturday afternoon, sushi and appetizers on the special menu are half off, and feel free to guzzle drink specials when they range in price from one dollar to six, tops. BTW, that includes beer, sake, and specialty cocktails.
