"Upscale" doesn't have to mean expensive or snooty. At El Chamol, chef Lamberto Valdez's contemporary Mexican restaurant in suburban Lake Worth, it means impeccable service and beautiful table settings — waiters who pull out your heavy wooden chair and unfold your napkin; painted Mexican dinner plates and pale-blue-and-green goblets. It means ravishing dishes arranged with an eye for color and composition and a chef who periodically emerges from the kitchen to greet customers or see to a table's special order. And the place is still as laidback as an afternoon in a shaded hammock. The Mexican-born, French-trained Valdez goes far beyond guacamole and chips to experiment with goat cheese and puff pastry, with cactus paddles topped with corn and shrimp, with lobster stuffed into a quesadilla, and with huitlacoche (fungus-filled corn) as a condiment. Even the guacamole is served with flair, handmade to order and scooped from a stone molcajete with corn chips the colors of the Mexican flag. Look for the coarsely chopped and lime-infused tomato salsa, their specialty margaritas, beans simmered all day and served in a cast iron pot, and tortillas that taste like the Mexico of your dreams..
