I'm fortunate that here in Pensacola, Fl there's at least three different bar/restaurants with over 100 beers on tap and bunch more in bottles. My personal favorite of the three is Hopjack's because of the damn good pizza they serve up and the good variety of local music on the weekends.
Here's the current beer listing. It's a mix of big corporate, regional and local beers. I'm a big fan of the Lazy Magnolia beers out of Mississippi and the local ones from Pensacola Bay Brewery as well.
