Oakland's Mad Oak is a laid-back bar spread across two floors of indoor-outdoor space. The upstairs-downstairs rooftop has plenty of seating, heat lamps and a bar on each level - not to mention T.V.'s for game viewing al fresco. Inside video games and a photo booth amp up the fun; outdoors cornhole is the name of the game. For eats, Mad Oak hosts chefs in six month pop-up stints.
