Locals know all about Keyport Fishery:
Dating back to 1936, these folks also had a booth up at the Fulton Fish Market in NYC. That is how my Dad learned about them.
This tiny little "fried fish" shack, served just about some of the best seafood anyone has ever tasted. Scratch that. Just about the best food anyone has ever tasted. Just that good. People would literally drive down from Connecticut just to get some.
Unfortunately the original owners finally sold the place. The quality of the food dropped. But we just went back. I don't know what changed, but it is back to very very tasty stuff. Not quite what the original owners had, but still probably the best fried fish you will ever taste.
I would particularly recommend the fish cakes, the crab cakes and the scallops. The fish cakes are just about as good as they used to be. Basically, until you have eaten these, you have never eaten a fish cake. They shouldn't even call it a fish cake, because it is just something else entirely.
They also have tons of fresh fish if you want to buy.
No seating! Buy some stuff, walk across the street and eat the food sitting right by the bay, like we regulars have been doing for years (me since the mid-60's). It may not sound like gourmet, until you take that first bite of the single best scallop (fried or otherwise) you have ever tasted.
