A Cuban sandwich — that majestic combination of ham, roast pork, Swiss cheese, yellow mustard, and pickles — is supposed to be so massive that you can't finish the whole thing. Most restaurants today offer a smaller, contemporary version, but for those of you with a hankering for an old-school sandwich, fear not. Mario's Latin Café on South Dixie Highway in Homestead still serves a heart-attack stack of deli meats and cheese on some of the freshest, softest Cuban bread in town, all for less than $6, 24 hours a day (closed Sunday). Go on — feast like a beast. Your ancestors will be proud.
