Lost and Found Beer Garden is beer and food place at 2040 Telegraph that opened in 2014. It includes a nice selection of beers, a small but tasty food menu, and a lovely beer garden behind the building. There is definitely a hipster vibe, but it's still a nice place to hang out.
Location: 2040 Telegraph
One wall of the beer garden (visible from Telegraph) features an Ernest Doty mural. In addition to seating and lots of plants, there's a ping pong table and other amusements.
At some point in the past (into at least the early 1980s) the building was a U.S. Army recruiting center.
Won 2014 "Editors Choice" Most Inspiring Place within a Beer Garden in Oakland Magazine.
