First you have to consider there are very few restaurants in Pt Arena, and most are not open early in the week. Then, being down on the water, and perched up on the second floor gives a great harbor view, until the sun goes down.
This is definately a place frequented by the locals, and being a very small village means everyone knows everyone. That sometimes results in spotty service as friends vist and chat with friends. The bar is often packed at sunset, so there's more visiting and catching up. Arriving after sunset can have the benefit of more attention from the serving staff. Luckily the daily specials are good and the kitchen is accomodating. If you want to take your time they're OK with that, there's no rush.
This part of the CA coast is mostly crabbing, with little fresh fish on any of the local menus. So, the crab cakes here are very good. The 'fresh fish' not as fresh as you'd find around a major fishing port.
But, overall, its an enjoyable experience out at a local place, with reasonable prices.
