Jojo's was a restaurant chain in the 70s. A slightly upscale Denny's/Golden Bear type place (I think they had a bar) that usually had a large bubble window in the lobby. I don't remember them tying in with the potato wedges, so the name probably didn't derive from them.
Not statewide, but "Beer Nuggets" (deep fried, slightly sweetened pizza dough nuggets served with marinara). Lived off them in college. Others have tried to emulate them, but they miss the mark set by Pizza Inn.
Had to do it, but that was the 70s. I was so surprised I was finally able to do it that I forgot to hand over hand down the rope & instead slid while holding on to the rope.
Hands on Fire!
