Mile Marker 28.5 on the Gulf side of Little Torch Key — that’s where Kiki’s Sandbar has been pulling people off the Overseas Highway for years. This toes-in-the-sand waterfront spot is the kind of Florida Keys bar that makes you extend your trip by a day. Live music runs every night, the tiki bar pours Mermaid Water and Kiki’s Rum Punch, and the cult-favorite Ahi Tuna Nachos — sushi-grade yellowfin on wontons with seaweed salad, wasabi cream, and eel sauce — will ruin you for regular bar food. Boats dock for free, the games beach draws a crowd all afternoon, and the kitchen cranks food until 11pm. Resident bull sharks patrol the pier. The vibe is unmistakably Keys.
