Fiesta Americana Cozumel All Inclusive's most casual restaurant just so happens to be one of the most authentic and popular as well. Modeled after the traditional thatched-palm seafood shacks that dot the Mexican coastline from Tampico to Cancun, this hot-spot for lunches and sunset dinners is perched right on the rugged shore, overlooking the blue ocean waves and mainland Mexican coastline nine miles offshore. Menu highlights include the spicy crab soup, ultra-fresh seafood cocktails of shrimp and conch and lime-marinated ''ceviches'' made from fish, shrimp, conch and mussels. Guest also munch on batter-fried fish filets, head-on whole fried fish and crunchy fried shrimp or fish tacos. Toss in an icy cold glass of Mexican lager, a frosty margarita or a creamy piña colada and you've got a perfect re-creation of the quintessential Mexican beach meal.
