Not a great selection in the world IMO.
The selection during the F&W festival was not bad, but most of those will not be available now. There was also nothing outside the big names most of us are already very familiar with.
Germany, England and Norway have nice beers, but I do not expect there is anything you have not tried before. England has the largest selection.
The beers over on the boardwalk at Big River Grille and Brewing Works are not bad and I heard you can do a tour of the brewing part of the place. If you have a local brewpub I doubt this will be anything you have not had before.
Maybe someone can recommend a place off site that has a large selection of beers.
