There's a new eatery in town near Sekiu Jetty. It is quite a nice place for being in such a remote location. This is a huge upgrade from having to eat at the Breakwater (aka Bilgewater) Cafe. Check it out. They even make their own bread!
This is one of your few choices for eating near Sekiu Rocks/Jetty. Don't expect great. The salad bar can be ok. We usually only stop here if we're staying in town or too hungry to wait to make it to Port Angeles to eat.
