Silvio's Pizzeria on Salem Road in Billerica operates as a full-service pizzeria and sandwich shop with an extensive menu beyond pizza. The kitchen turns out calzones in both regular and large sizes—the Italian calzone layers mortadella, hot ham, and salami with provolone and mozzarella, while the Four Cheese option combines ricotta, mozzarella, provolone, and romano. Beyond calzones, the menu spans deli cold cuts, egg sandwiches, fresh salads, and a sizable appetizer selection including wings in multiple styles (plain, hot, BBQ, ranch, honey garlic) and boneless fingers. Hot & Spicy Chicken Calzone uses what they call their special hot sauce. Steak and chicken salads offer protein-forward options, and the deli roster includes homemade chicken salad and tuna alongside standards like roast beef and Italian.
