They actually have 2 locations. Mountaintown Station is a Brewpub with pretty decent food, right near the Downtown Area. The other is a bar/brewery which is considered the production brewery. That one is west of Mission on the road that Meijer is on (name escapes me ATM).
The beer is decent, but not unusual or outstanding IMO. They have a standard selection last time I checked.
I generally pass their beer by at the store, because there is usually something "better" to pick up. I should probably try them again. I do like to stop by the bar or brewpub when I'm over that way and can make the time.
