If you're ever in Portland, Oregon, get a Miss Piggy from Flying Pie Pizzaria. With extra garlic and spices. Does not do wonders for one's social life, but it is by far the best pizza I've ever had. The best pizza I've ever found in my beloved home state of Wyoming was at a place called Giansanni's in Casper, sadly defunct these past many years. The best currently is the Ron Swanson from the Gannett Grill in Lander. P6 Station in Thermop has pretty decent pizzas too.
I believe all three places have pineapple pizza available for all you strange people who require fruit on your pizza.
