Mmmm pie! Or, as my friend Don says, "Pie for Strength!"
Cyrus O'Leary's is restaurant in Spokane. When the MOA rally was there, we went twice for pie, it was so good!
edit: I just looked this up, unfortunately the building was sold and the restaurant closed in 2011, but you can still buy the pies.
In Tigard, OR (just south of Portland) is Miller's Homestead. Great food and especially, great pie!
