I\'ve been to one of those restaurants before.
When I was only a few years old (around 1967-1969 probably), I saw a children\'s book about "Little Black Sambo." I don\'t remember if it was handed down from my grandparents, or if some cousins had it or what. I do remember the book very vividly though. I was so young I didn\'t know the racial stereotype was offensive, so other things in the book made a bigger impact on me. As I recall, Sambo is harrassed by some tigers, so he gets them to run in a circle, and the tigers turn into butter!
I\'m not making this stuff up. Anyway, my parents disappeared that book pretty shortly thereafter. Maybe I\'ll see if I can find something about it on the Internets.
EDIT - It\'s still in print. (Check Amazon)
