There are three certainties in life: Death, taxes, and new hamburger joints opening in Miami. And just as the manner of death and amount of taxation differ from person to person, so too do the burger emporiums. Burger & Beer Joint, part of the original wave of boutique burger bars that burst upon South Beach back in 2009, is distinguished by its superior hamburger (a second B&B has since opened in Mary Brickell Village). It's a ten-ounce, certified Angus beef prime patty that is assertively grilled and garnished according to your preference in rock song. Thunder Road? That brings smoked Duroc pork-belly bacon, American cheese, bourbon barbecue sauce, and, like all burgers, a side of skinny fries ($14). Hotel California? The burger gets dressed with guacamole, ranchero salsa, grilled red onion, cilantro sour cream, sharp cheddar, and a sunny-side up fried egg on a brioche bun ($14). Mustang Sally cuts the portion to eight ounces but ups the beef quality to Wagyu, with red onion marmalade, prosciutto, and Brie ($16). There's an ahi tuna burger, a portobello mushroom burger, a turkey burger, a chicken burger, and a Wagyu burger with foie gras, black-truffle demi-glace, and duck-fat fries ($32). Octane chicken wings, beer-battered onion rings, and mac 'n' cheese are among the snacks. But remember, this is a beer joint too: The selection, 99 strong, is one of the most extensive on the Beach. Booze-boosted shakes and rock 'n' roll tunes fuel the fun at this local favorite. Finally, we appreciate that B&B has a big heart: Ten percent of all 2012 sales from the kids' menu is donated to help St. Jude Children's Research Hospital.
