That sounds a little high to me - sure, I'd bet it's around 50%, but there's plenty of other things going on, whether it be tax evasion, prostitution, fraud, etc. Political corruption, for example, is common in the developing world - give your buddy the contract to build a road/dam/whatever, cut every corner possible or just completely fail to deliver, and if properly laundered, there's no way for the government to recover the funds. And I don't know if anybody would go to the trouble of using a restaurant, but "asset protection" is a thing in wealthy circles, sometimes due to involvement in high risk businesses (porn, file sharing) or just being worried about an impending divorce.
