San Francisco, California
This speakeasy hidden inside the San Francisco Giants’ AT&T Park makes box seats look absolutely pedestrian. You can actually spot the bar if you squint hard enough—it’s behind the outfield scoreboard. Accessed through what appears to be an electrical closet door, the Gotham Club is a members-only venue, featuring a full bar, bowling alley, arcade, billiards room, and naturally, baseball-shaped ice. Convince your closest Giants fan to sign up so you can come along. You know, in case the game is getting a little slow.
