Hot Box Pizza & Roast Beef operates out of Bow Market in Somerville's Union Square, run by the team behind Mike & Patty's, the Bay Village establishment. The menu centers on bar pizza and roast beef sandwiches—the latter served North Shore–style with BBQ sauce, mayo, and American cheese on an onion roll. Pizza options range from a straightforward tomato sauce and cheese to variations like Buffalo chicken with ranch drizzle, spicy pickle with sambal, or the Onion & Mushroom. The space shares quarters with other Bow Market vendors, allowing you to pair food with beer and wine from neighboring businesses. Hours run split shifts most days, with extended evening service on weekends.
