What started as a tiny pizza shop in Portland, Maine, is now a fan-favorite across Boston and Cambridge for its unique pies and perfectly crisp crusts. OTTO combines unconventional toppings like mashed potato, bacon & scallion, and three-cheese tortellini to create pizzas that are as flavorful as they are inventive. The topping combos might seem weird at first, but take one bite and you'll be hooked. The menu splits its options into pies with meat and pies with vegetarian toppings, and you can request to hold the cheese or use gluten-free crust, too. Be sure to grab a drink from the craft beer and wine selection.
