The upscale end of Marathon’s tiki bar scene, TJ’s sits at Tranquility Bay Beach Resort on the Gulf side with views of the famous Faro Blanco lighthouse framing every sunset. The covered tiki bar specializes in frozen tropical cocktails, the beachfront seating puts toes-in-the-sand within reach, and the Caribbean shrimp, Blackened Shrimp Salad, and seafood nachos from the lunch menu make a solid case for staying longer than planned. The Gulf of Mexico view is the real draw — some of the most spectacular sunset light in the middle Keys, enjoyed from one of its most comfortable perches.
