Tomatoes $16 per kilo in Luanda
When you think of the world's most expensive cities, the dusty Angolan capital of Luanda seems an unlikely contender.
Potholed, chaotic and still scarred by decades of civil war, the city has little of the glitz and glamour of Tokyo, New York or Moscow, and an estimated half of Angolans live on less than $2 a day.
But despite the obvious poverty and sprawling slums, Luanda still manages to boast some eye-wateringly high prices.
When Wina Miranda moved from Indonesia to Luanda in 2008 she knew the city was going to be expensive, but she was not prepared for quite how expensive.
