Where do you go when you've run rings round the bathhouse and the disco ball no longer beckons? Reflecting the graying and -- gasp! -- mellowing of Vancouver's boomer-age gay crowd, the hottest new hangout for gays is, well, a pub, the Fountain Head, located in the heart of the city's gay ghetto on Davie Street. Open a little over a year, the Fountain Head offers excellent microbrewed draught, good pub munchies, and a pleasant humming atmosphere till the morning's wee hours. Limited cruising has been known to happen, but more often customers come with friends and have things other than intimacy in mind. Indeed, most of the bragging at the 'Head involves the size of people's portfolios.
