I just heard from Verona that Papa's Pizza in south town Corvallis has gluten free pizza. It's on their website, too! That certainly sounds like it's worth checking out. Pizza is one of those hard things to not have since so many people in the U.S. think of having pizza parties as a way to celebrate.
For pizza at home, I like Amy's rice crust pizza, especially if you add on toppings. :)
