If you're going to haul out the ego and deem your restaurant — or, in this case, deli — a "masterpiece," you'd better live up to the superlative. There's a reason that this Highland sandwich shop commands lines out the door, making it nearly impossible to snatch up one of the few tables or counter stools: The sandwiches really are that good. Exhibit A, the Italian, featuring thin, nearly translucent Parma prosciutto; smoky salami; the rich fattiness of mortadella, pepperoni and capicolla; sheets of provolone and peppery arugula, lettuce and slivered red onions. It all comes stacked on crusty ciabatta slicked with vinegar and oil and smeared with a black-pepper-spiked aioli — and is nothing short of a masterpiece.
