Sample Flathead Lake Brewing's legendary beer – including their unique sour-series inoculated with yogurt cultures (it works, mostly) – at their sharp location overlooking the northern end of the lake. This is the New Montana in all its glory: great views, great beer and reasonably priced food like duck breast with melted goat cheese and mango chutney.
In the name of very arduous research, we tried all their beers and our favorite is Two Rivers Pale, but we'd happily taste them all again just to be sure.
