La Sirenita - View this location on map 'The Mexican cooking at this Riverdale diner is the real deal. If you think every Mexican dish is really the same dish—variations on a theme of meat, beans, cheese, and rice—you’re due for a trip to this Riverdale joint, which should banish all memory of Tex-Mex haunts that make each plate indistinguishable from the last.' Washingtonian 4911 Edmonston Rd., Hyattsville, MD Budget, Restaurant
