My Great Lakes Brewing Guide shows a Mishawaka Brewing (brewpub/microbrewery). The location is 3703 Main Street, Mishawaka, IN -- 574-256-9993 (Mishawaka is right next to SB). But have not been there.
Not too far away in Michigan City is Shoreline Brewery which I have visited and enjoyed very much. It is just a few blocks from Blue Chip Casino.
A bit further away, but if you are in that neck of the woods, you should consider a pilgrimage to 3 Floyd's Brewing in Munster, a brewpub/microbrewery renowned for its creative/big beers.
