Runner up is the the agglomeration of almost 300 bars and pubs in the Altstadt of the town where I was raised, Düsseldorf, Germany.
I now waste away in Margaritaville, also known as beautiful downtown Catemaco, Veracruz, Mexico. With a city population of less than 30,000 and an average daily income of about 3 Happy Meals from McDonald, the town boasts of almost 200 cantinas, bars, nightclubs, beer dispensories, etc.

The Catemaco municipio government probably spends considerably more money on drunk disturbances than it receives from licensing fees, yet tolerates an almost daily increase in drinking places.
Go ahead, have a cold one on me!
