We ate at Dooger's yesterday. The Clam Chowder is great!!! The waiter said, "It's been gluten free for 34 years and people have just recently started asking if it was GF."
I also had the Fish and Chips with steamed veggies instead of fries because the fryer isn't a dedicated fryer. See photos.
They also have a restaurant in Warrenton, OR, which is near Astoria.
