For me it was Mr. Gaddies (chuck E. Cheese without the rat) in Sapulpa. Saw one driving through Texas 4 or 5 years ago and made me smile.
Dude, Mr Gaddies was a weekly mandatory for us in Lake Charles. Cheap enough to feed a fam of five on spare change! Now they have Gaddie-Town's all over the place. Pizza is still the same. Good stuff right there.
