Nick's Pizza operates out of a modest storefront on Merrimac Street, where the LaBarba family has been turning out square pies from an Abruzzo recipe for years. The hallmark is the crust itself—medium thickness, cooked in large rectangular pans—paired with a red sauce and cheese blend that's developed a steady following across the region. With 26 toppings to choose from, there's room for both traditionalists and customizers. The place has recently been inducted into the Pizza Hall of Fame.
