Mary's Pizza Shack serves a variety of homemade Italian food including pizza, pasta, sandwiches, soups, salads, breadsticks, appetizers and desserts at moderate prices. The dressings, sauces, dough and soups are all made from scratch using Mary's original recipes from her original shack. Each item is made to order and there are no heat lamps, frozen dough or canned sauces. All pasta meals include soup or salad, and sourdough bread. Signature items include "baseball sized" meatballs, pesto breadsticks, salads, linguini with clams, gnocchi, homemade soups and desserts and of course the legendary pizza!

All Mary's Pizza Shack locations have open kitchens, so that customers can watch the chefs make the pizza and pasta (and Mary's pizza cooks are known to give kids free salami slices). Mary's Pizza Shack continues Mary's tradition of having free breadsticks in a basket at the front counter for guests to enjoy.
