Spaziano's Pizzeria Catering, Haverhill

The reviews of Spaziano's leave little room to doubt its pizza's popularity. "The slices are bountiful, sinful, and delicious looking," reads one, whose author ordered the Miss Piggy, a pie starring Cheddar, chicken, bacon, and mozzarella latticed by drizzles of honey-barbecue sauce and ranch. Several others praise the sweet pizza sauce, which—along with the restaurant's thin, crispy, and slightly chewy crust—helps set Spaziano's pies apart from all the Greek- and Sicilian-style slices around.
