Quoted from kcZ:Pyramid Scheme in Grand Rapids, MI is nice (probably OK for an 11 & 14 year old).
They are a bar and have concerts and stuff there, but if you go in the day it's pretty mellow. I've taken my wife and one-year-old there before. Great selection of A-listers. Probably a couple dozen titles. Lots of B/W and Stern. Not a bad suggestion!
Quoted from 67cutlass:I'm going to try to go there when I go to Pinball at the Zoo. This time the family is not coming for that.
Too bad you can't bring 'em to the Zoo. That's a great family-friendly show. Very relaxed atmosphere there. I'm a little biased, as the event artist, but it's my show of choice around these parts.
Finally, for selection of games, it's tough to beat Clay's VFW show:

Cool to hear your kids are really getting into pinball!
Take care and safe travels,
