There are half a million Cubans in South Florida and something like four decent Cuban restaurants. OK, maybe five. Evidently, the ex-pats have far better things to do than to open cafés where everything on the menu costs less than $15 like manage gargantuan sugar farms, run for office, or study for the Florida bar. Who can blame them? Standing over a hot iron pressing sandwiches all day is no picnic. You Ôd have to, in fact, be a crazy Italian to want to do it, especially to do it twice. But when Sam Mancuso opened a second outlet in Boynton Beach last year (the first Crazy Cuban was in Vero), he answered the prayers of many a hapless local who, when faced with a hearty appetite and the contents of his change jar, thinks inevitably: Cuban sandwich ($5) with extra pickles (free). If the jar runneth over, he might even splurge on a Cuban Special ($6.25), which adds sliced turkey breast to the classic ham, pork, Swiss, pickle, and mustard combo. Both, of course, are served on excellent, deliciously oily pan Cubano heated, smooshed, and crisped in a sandwich press so the textures and flavors that have rightly made this neat little meal a staple of penniless hacks everywhere are thereby perfected.
