The best lunch on the beach is at Playa Lanchero, a long-time institution on Isla Mujeres. Whole fish and other meats are cooked over an open pit grill with Maya-style achiote spice rub and served family style. The guacamole is the best in Mexico. We treated our friend Plutarco and his family to a meal here. We always ask for his taxi when we come to Isla Mujeres.
