Variations on a simple theme can lead to much awesomeness: think of all the music based on the blues 12-chord progression, or Duplos...wait, those sucked, there was only the four one and the eight one! For an eatery venturing into Lego territory of burger iterations, hit KB Burgers & More.
From a guy who wanted to provide cheap eats to all the fine peeps in Key Biscayne, counter-service KB rocks kiteboards on the wall, extreme-sports-playing flatscreens to watch people fall off them, an open kitchen, a juice bar, and a menu that elevates the burger by adding tons of variations that're globally inspired, thus threatening to do the same to your silhouette. 6oz Angus highlights include the Roma (organic arugula, tomatoes, shaved Parm) and Colombian (mozz, ham, bacon, pineapple, chips), while there's a crop of kinda-nuts specialty guys like the Gurkha (lamb, curry seasoning, mango chutney), the Billionaire (ground filet mignon with truffle foie gras center), plus the Juicy Lucy (two patties w/ cheddar & American between), all of which come on a sesame seed or whole wheat bun, ciabatta, or a lettuce wrap -- most of whose lyrics focus on growing up dirt poor, and contending with hoes. "And More" means grilled free range chicken paillard, meat lasagna with bechamel sauce, plus sandwiches like the Key Biscayne Burger (snapper marinated in lime juice), dill-marinated salmon, and mango/red onion/cilantro-abetted wild shrimp, although that's really not the nicest thing to call the midget from Jackass, he's nearly a person too.
KB also offers what nature intended to accompany a burger: a simple beer selection of Brooklyn Lager, Sam Adams, and Brazil's Brahma, plus blown-out desserts like banana splits, milkshakes, and ice cream sundaes -- attack them with Brio, and it'll ensure your car never becomes a Playmobil.
