Chef Mark Falgoust is a good Cajun boy, with strong Cajun flavor sensibilities and a love for ham.  He is also a sandwich whisperer.  On a recent visit to Grand Isle Restaurant, I perused the menu and then asked Mark what I should eat.  Without hesitation, he mentioned his "Butcher Special" sandwich of sticky, house-cured ham with melted cheese on New Orleans French Bread. Smoky, sugary and deliciously tempered by the tang of the melted Swiss, this was no ordinary ham sandwich and it's a special that tends to float off and on the menu, though Chef Mark gets so many requests, he may make it a regular menu item.  Oh and in case you're wondering, Mark and the folks at Grand Isle know a thing or two about a good sandwich, they took the top honors at this year's Po-Boy Festival, with a ramped-up Vietnamese inspired Banh Mi (sandwich), decked with fried, spicy-sauced shrimp, pickled vegetables and other garnishes, called the "Shrimp Caminada."  Sandwich genius ad yes, a sandwich whisperer.
