The house rules

Pizza built with science. Served with a story.

Chef and food scientist Ray Sierengowski built Underground Pizza Truck around two things he knows well: how flavor works and how a memorable experience should feel.

Every pie starts with a carefully fermented dough and finishes with ingredients inspired by travels, restaurant kitchens, and a lifelong habit of asking, “What would make this better?”

Private events and public stops

Pizza worth leaving the password for.

Weddings, birthdays, corporate events, community gatherings, and the occasional public pop-up. Tell us what you are planning and we will help shape the right service.

The full lineup

The menu

Our three-day dough is baked hot and fast for a crust that is crisp at the edge, tender inside, and sturdy enough for the good stuff.

Bring the speakeasy to you

Made for a crowd.

We bring the truck, the ovens, and the full Underground experience. You bring the people and a place for us to park.

A business with a bigger purpose

The Ben Initiative

Underground Pizza Truck began with a father thinking about his son's future. Ray wanted to create the kind of workplace where people with special needs are seen for what they can contribute, given meaningful responsibility, and supported as they grow.

That commitment is built into the business from the start. Every event helps move the mission forward, one shift and one opportunity at a time.
