The most Cuban sandwich of all isn't the eponymous one. It's the frita. And though Miamians will argue their favorite frita spots all day, there's one that does the frita like no one else. Sometimes you want it quick and cheap, and that's where Cuban Guys comes in. With four locations from Hialeah to Kendall (and one opening soon in Miramar), they know what makes this sandwich so sensational, perfecting it in fast-food form for $3.99 a pop (and for only $3 Tuesdays after 4 p.m.). Let's start with the bread: A fresh-baked Cuban bun displays the restaurant's logo stamped on top. The beef, seasoned to perfection, is never frozen. It's hand-shaped into patties each day. And those crisp potato sticks are cut and fried in-house, so they're never soggy. Make it a deluxe with mayo, tomato, and lettuce. And if one frita isn't enough, you can always go for the doble ($4.99). Piled high with double the ingredients, it's one of the sexiest — and cheapest — fritas in the 305.
