In the heart of Historic Pass-a-Grille on St. Pete Beach, Shadrack’s is the undisputed dive bar king of the Pinellas County barrier islands — a red neon-bathed, cavernous bar that one reviewer memorably described as a wooden shack turned inside out, with a roof inside the building and wooden shingles on the walls. Since 1972, fishermen, bikers, artists, and writers have converged on this 114 8th Avenue institution for cold cheap beer, a jukebox cranking country and classic rock, pool tables, darts, foosball, and pinball. The highlight of the monthly calendar is the legendary first-Sunday Bloody Mary bar — pay for your vodka, grab a skewer, and load it with bacon, meatballs, wings, olives, cheese, and whatever else you can fit, then pick your mix from four varieties. Two separate happy hours run from noon until close. The Gulf beach is two minutes away. Dogs welcome. Cash bar prices that belong to a different era in the best possible way.
