Best known for top-shelf Italian salumi, cheeses and pantry items, Casa Italia secretly constructs some of the city’s most bodacious sandwiches. But don’t expect enormous Italian-American hoagies. Casa Italia’s artfully constructed sandwiches typically highlight one or two ingredients, allowing their full flavor to shine through. A favorite: the $6.99 mortadella and cheese. Even with the provolone, the lettuce, oil and vinegar, the crusty bread, it’s the ultra-porky flavor of the pistachio-flecked mortadella—the pride of Bologna—that shines.
