There are literally dozens of frita joints scattered along Calle Ocho, some of which claim to be the reyes (kings) of fritas while others boast they're the magos (wizards) of the spicy Cuban hamburger (curried beef and fried onion topped with papitas, freshly fried potato shreds). But Fritas Domino has an identity all its own -- it's an original. Recently a fortysomething gentleman walked up to the counter and asked for the managers. He wasn't complaining, he just wanted to say hello. The man wondered if the managers remembered him. He used to work at Fritas Domino's original location, Calle Ocho at Twelfth Avenue. The Espivil family, who opened it in 1961 as a place where exiles could find authentic Cuban food, had given him his first job off the island. The conversation moved from sentimental recollections to fists-down declarations regarding Fritas Domino's stature among Miami frita shops. Referring to a competitor, the former worker emphatically declared, "They say they're kings, but they're not Domino!"
