The carefully landscaped complex appears so collegiate that it's affectionately known as LSU—short for Levi Strauss University. Lawns complement the redbrick buildings, and gurgling fountains drown out the sounds of traffic, providing a perfect environment for brown-bag and picnic lunches. The Vault, the lobby exhibition space, has displays focusing on the history of the company, including jeans that saw the gold rush, videos about Levi's marketing and textile restoration, and temporary displays such as the jeans made for celebs like Lady Gaga and Elton John. You can purchase Levi's and Dockers straight from the source at the cozy lobby boutique. The wonderful Filbert Steps to Coit Tower are across the street.
