Water laps softly against bobbing boat hulls. A setting sun turns clouds into wide streaks of orange and red against a purple-blue sky. None of it matters once you hear the sandy, gritty crunch of pale-orange stone crab claws being crushed. The cool evening breeze whooshing in off Biscayne Bay doesn't matter when you learn that Monty's Raw Bar in Coconut Grove sells medium Jonah crab claws (or stone crab claws in season) for $4 during a 4 to 8 p.m. happy hour on weeknights. You'd trade the water views for a blighted warehouse as long as the claws remain cheap and the oysters, clams, and peel-and-eat shrimp are still a buck. Yet add the views, the half-priced cocktails and discounted beer, and the din of a hard-drinking happy-hour crowd (many of them UM students), and you'll swear off those chichi seafood towers forever.
