No cover charge, cheap drinks and a longstanding reputation for transforming singles into couples (at least for the night) makes this SoMa hangout a prime place to hunt for that dirty, rotten scoundrel on the loose.

Something?s rotten in Denmark when a contentedly slovenly mate takes a sudden, inexplicable interest in grooming habits.

When little miss prude heads to this Cow Hollow spot best known for incorporating pole-dancing techniques into its fitness classes, one thing?s for certain: Somebody, somewhere is reaping the fruits of her hard work.

It?s only natural for cheaters to gravitate towards this chic, reservations-only bar in one of downtown?s trendiest hotels. Why? Because it was designed by Ian Schrager, the nightlife impresario responsible for the bastion of 1970s philandering that was Studio 54. And should the cheater?s mere eye-wandering metastasize into something more, there are plenty of rooms just overhead.
