I love this place. I discovered it about 6 months ago (only have been playing for 1 year) and I've been there at least once a month. It's a 30 to 40 minute drive for me. I usually get lunch/dinner at one of the MANY restaurants that are right off Central Ave (personal favorite = Tavern on France). Blainbrook also has *delicious* nachos. I've had those a few times before or after playing pinball.
As far as pinball goes, Blainbrook Bowl (BB) is a pinballer's dream. There are almost 50 games from the 70s through today. Just about every game is in great condition. There is a clipboard with a work-log hanging up where you can report issues with the games if you find any.
My current favorites are South Park, Addams Family, Dracula and Jurassic Park (no Match/Replay?). I miss Fish Tales.
The only sad thing about the place is that I never see a good crowd playing pinball. It could just be the hours that I'm there? I'd love to see that place packed and generating $$$.
