Sorrento's is a brick oven pizzeria on Thoreau Street in Concord with a practical approach to dietary restrictions. The menu spans traditional pizzas, specialty pies, appetizers, salads, wraps, subs, and pasta, but what sets them apart is their explicit accommodation of common dietary needs: gluten-free pizza crust, vegan shredded mozzarella, meatless sausage crumbles, and meatless chicken fingers are all available. They also make Five Cheese Ravioli. The kitchen uses shared equipment, so they ask that customers with food allergies note them when ordering. Typical wait times run around 20 minutes, though Friday and Saturday evenings can stretch to 35 minutes. Online ordering is available for Concord, Acton, and Harvard.
