I can tell you living in south america that this is true. Three drinks esp. caiprinhas even at the expensive places would be about $13, $8 or $9 on promo. Cover for the fancy place is $17. Bottle service is $34.

Plus the bombed out building post war Berlin industrial feel is 1. Real, and 2. free for the promoter and the drinks are cheaper there. Yes, that's real barbed wire, and yes, its really electrified.
