Club Profitability

I'm really interested in learning the metrics of how a club makes money and what model ends up being profitable. It does seem that unless the local politicians restrict the clubs, they only seem to grow in number. So somebody sees this as a good business. Here in a pretty unregulated local strip club market, even when clubs close, they only seem to reopen under some other moniker with a different vibe theme a short time later. But I also presume that part of the interest in these business is that they are high cash turnover businesses, and therefore great for money laundering (and my part of the world just so happens to have a big need to launder money). So maybe these clubs don't have to turn a profit and the metrics of achieving profitability are out of the window. I'd be interested in any business article write ups on the subject.
