The Video Game museum is pretty cool. Just to warn you though, it has virtually no pinball related stuff.
Most (but not all) of the exhibits are home console related.
Beyond the exhibits, it does have a decent "mini-arcade" with about 25 '80s arcade games, but all video, no pinball.
It actually has MY original Game-Boy Development system on display (my former boss donated it to them when the company folded).
