I'd say Spain has the most drinkers (I used to live there and have been there many more times than I can count). You can't spit without walking into a bar or a pub (At least in Madrid). Beer is cheap and plentiful. Pluss you can drink anywhere.

The wife and I leave for Madrid this Tuesday (Of course I'm bringing my guitar, I have many jamming buddies over there). As soon as I get off of the long booring plane ride (From San Francisco) I'm gonna have me a cigarette and enjoy that light headed feeling of not smoking in a few hours, And a Mahou (A very good Spanish beer). Then later on that night after a nice shower I'll be going first to the La Maripepa (A cool bar) Then off to Afterdark (My favorite Heavy Metal pub where they play Heavy metal videos on two huge screen tv.'s)
