A bunny chow is a curry served in a hollowed-out half-loaf of bread, usually with a side salad. One theory of how the name came to be suggests that "bunny" is a corruption of the word "bania" (referring to Indian traders), with chow referring to food -- so literally "food from the Indian corner shop". Various stories suggest that restaurants would serve curry out of the back door to black people in a half-loaf of bread instead of a plate, so no cutlery or crockery to return.
No visit to Durban is complete without a bunny chow for lunch. (From my response to a comment below)
