Let's go play pinball up in LA, near Echo Park.
Pins and Needles has 24 machines, a good collection. Hours are announced early-ish each week. Typically they end up being evenings (after 8pm) on Tuesdays, Thursdays, Fridays, and Saturdays. That means the date and time isn't 100% solid until the week we go.
Somebody did a youtube-o-mentary. It looks like it'll be a good time!
