There was a Sambo's restaurant where I lived, too. By the time I really remember it in the '70s I think its promotional material was based around a tiger character.
This is not really non-PC but my wife and I were talking about it the other day and it seems so bizarre now I'll mention it anyway: My parents didn't smoke, but one of my grandpas did. When I was a little kid in the early '70s, my mom had some green glass ashtrays in a drawer, and when grandpa would come she'd get them out and he'd sit right there in our living room and puff the room so full of smoke that my eyes burned. And we didn't think anything of it! It almost doesn't seem believable, now.
