Our First Cafe
The Proof Lab campus is a tribute to all the wonderful things about Marin and the site of our very first cafe. Coincidence? We think not.
We designed our first cafe as an homage to the outdoor and surf communities of Mill Valley. Local craftspeople shaped reclaimed redwood into our surfboard fence, greenery was provided by a neighboring plant nursery.
