They look so creepy that most folks won't touch 'em, but that's just fine — more for us! A langoustine looks like a cross between a spider and a shrimp that deep down wants to be a lobster — could be it's the animal that inspired T.S. Eliot to imagine a "pair of ragged claws scuttling across the floors of silent seas." At Bova Prime, they don't fuss around and try to make it pretty for you: These suckers are presented head to tail, with their tickly feelers fanned out on the plate. The langoustine is not a native of Florida, and you don't see it on many menus here. It's more precious than our lumbering stone crabs and slow-witted spiny lobster; these are the fairy folk of the shellfish world. Sizzled over charcoal and served with a tart green mache salad ($23), the meat in their little tails, each about the size of your middle finger, is as soft and sweet as a breathy endearment whispered on a deserted beach.
