Gillette Brewing Co is pretty awesome. I like their beers and Nate Hardy is one of the brewers. They have also moved Pour Brothers across the street from their brewery.
Prairie Fire Brewing on the other hand has IMHO very bland beers. And the service has been far from friendly. I think they have a ways to go before they are a good brewery.
The only one I have heard of but haven't tried is the brewery in Skyline Grille. I've not heard much from them though.
