Authentic Chicago Tradition
NOT DEEP DISH.
THIS IS CHICAGO'S REAL NEIGHBORHOOD PIZZA.
For generations, Chicago locals have gathered in neighborhood taverns over thin, crispy, square-cut pizza. It's the style Chicagoans actually grow up eating—and the tradition we're proud to bring to Portland.
Thin & Crispy Crust
Rolled thin and baked until perfectly crisp, creating the signature crunch that defines authentic tavern-style pizza.
Square-Cut Slices
Forget giant wedges. Tavern-style pizza is traditionally cut into shareable squares, perfect for gathering around the table.
Toppings Under The Cheese
A true Chicago tradition. Toppings are layered beneath the cheese, locking in flavor and creating the perfect bite every time.
Our Story
A PLACE BUILT AROUND COMMUNITY.
MORE THAN PIZZA.
Proof was inspired by the neighborhood taverns of Chicago—places where great pizza, cold drinks, sports, and community come together. We set out to bring that same spirit to Portland and Beaverton, serving authentic Chicago tavern-style pizza in a welcoming atmosphere built for gathering with friends, family, and fellow fans.
From our thin, crispy square-cut pizzas to our commitment to hospitality, everything we do is rooted in creating a place where people feel at home.
