Shawn, are you familiar with Dave Portnoy and the "One Bite" app? Portnoy does pizza reviews mostly on the East Coast. They post at least one review per day on YouTube. But, you can go on their website to search the reviews without the app.
The reviews for Portland are all user reviews and pretty sparse.
