That chain used to be called Bob's Big Boy. I first ate at their original restaurant in Burbank, Calif. in 1957--and my last visit there was in 2018. In the '60's and '70's, Bob's Big Boy restaurants were found all over Southern California, but they began to disappear in the '80's, and now there are only about five left.
Yeah, we used to have one here in the 80’s and 90’s.................
There are two Big Boy restaurants with an interesting history between them:
