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.
