My 8 year-old son watches a lot of YouTube videos of the old classic video games (Donkey Kong, Pacman, Galaga, etc) so he always wants to find places that have these video arcade games. He also loves to play pinball machines, so my wife found the Seattle Pinball Museum while doing a Google search which seemed like a good place to check out.
First, I was a bit wary of visiting this place since it is in the International District of downtown Seattle and I hate having to find parking there. But luckily, I was able to find a perfect parking spot right in front of the Pinball Museum's front door. Once inside, you see lots and lots of pinball machines lining the both walls of the narrow shop. You pay a flat fee of $10 for adult and $7 for children under 12 and can play as much as you want. They start with the older machines on the right wall by the door, and as you move further back and around to the left wall the machines move forward in time from old to new. They've got great classic games, and my son liked the two Simpson's pinball machines. And for a break, they also have Pacman and Galaga arcade games in the back of the shop.
You can get snacks there (Bottled water and sodas for $1, and chips to munch on). They do sell souvenir T-Shirts at $22 a pop which was steep, but I bought one anyways for my son to support the local business. We were there on a Friday afternoon, and it was fairly busy (and loud!). In all, my son had a great time and wanted to come back again.
One thing to note, the do have private parties there so be sure to call ahead to make sure they aren't closed to the public. And also be aware that you may have to drive around a bit to find parking on the street or in a paid parking lot nearby.
