At the Seattle Pinball Museum, everything may be behind glass, but nothing is hands-off! The owners have a rotating collection of pinball machines, usually about 30 at a time, ranging from old-timey wooden boxes to modern games with tons of bells and whistles. There's even an arcade game or two tucked in the back for you Pac-Man fans. $13 adult admission gets you an all-you-can-play wristband, but be warned: hours can melt away quickly in here, and only metered street parking is available. You can also rent the museum for parties or events, and pick up some cool T-shirts for a unique Seattle memento.
