Went to one of the local brewpubs here and they had a pils, a helles, a vienna, and an Octoberfest all on at the same time. I did a flight of them (and their hefe & English porter) in your honor & they were all pretty solid. I'm not up on the stylistic accuracy so can't speak to that, but all super clean.
It's called Heavenly Goat Brewing in South Bend/Mishawaka - got off to a pretty rocky start (not necessarily the beer but in running a business) but they seem to be getting their act together.
