I have heard of these guys from friends in Johannesburg but have never tried 'em. Might actually be in the District/NOVA area early next year, so thanks for the heads-up.
Since then, I've been gladdened to happen across and eat in Nando's restaurants in Mauritius (which is easy enough to expect, as Mauritius is a suburb of Johannesburg), Singapore, Kuala Lumpur, Dubai, London and Dublin. I never did figure out why Nando's is not in Hong Kong, which is an expected destination based on those other markets.
It's because each of those cities (except possibly Dublin, but this is one of the reasons why they're re-thinking their EU membership) has a substantial Muslim (ie can't eat pork) population and HK, like the rest of the PRC, is trying to reign in their Uighurs. If NOVA and the District could reign in their wiggers. . . wait, there's another thread for that. Sorry.
