It's nice that the proprietor, Maria Narvaez, learned to cook by watching her mother in their pueblo of San Luis Potosi, Mexico, and that after a stint in Houston, she and her husband, Jose, ran a restaurant in Chicago named after their son, Marlon. It's even nicer that they moved to Florida and opened an affordable, authentic joint on the Hollywood Broadwalk, naming it after the first words that spilled out of Marlon's mouth when he saw the fine-looking ladies passing by on the beachfront: mamacitas. Today, it's nicer still that this chill establishment offers sports on TV and live music four nights a week (salsa, merengue, bachata) and that a spontaneous dance party is likely to break out on the sidewalk as you wolf down a giant whole fried snapper. But these details are all best enjoyed when sipping on the signature drink, a tequila-drenched frozen margarita topped with lime, a straw, and an upside-down Corona. This concoction is called a "Rompe Nalga" ($15 for a medium, $23 for a large), which translates literally as "break buttock" but means, essentially, it'll kick your ass.
