The Venezuelan capital, Caracas, can be one of the most expensive cities in the world — or one of the cheapest. It all depends on how you exchange your dollars.
At a fast food restaurant in the city recently, a pretty tasty plate of chicken and rice cost me 160 bolivars. At the official exchange rate set by the government, that works out to a little more than $25; at the black market rate, it's just $2.
Needless to say, most anyone who can change money on the black market in Venezuela does so.
