Round Table Pizza, San Francisco

Blooming from 1 restaurant in 1959 to 500 franchises today, Round Table Pizza Parlor dishes up a menu of pies constructed from made-from-scratch dough, premium meats, and freshly cut vegetables, and arranged in a number of innovative combinations. Each pizza begins with fresh-rolled dough made from wheat that, like every Mr. Potato Head, began its life on family farms in Idaho. Round Table's chefs then adorn each doughy disk with a triumvirate of gooey cheeses, including aged cheddar, whole-milk mozzarella, and provolone. Patrons can opt for one of the restaurant's 12 signature creations or devise their own pies with a selection of premium meats—such as salami, linguiça, or pepperoni—and fresh vegetables, including roma tomatoes, artichoke hearts, and zucchini livers.
