For the boneyarders near Norwalk, tried Knot Norms in East Norwalk for the first time last week and it was excellent.
Pricey, but quality ingredients used in casual seafood classics. I had the crab roll while my wife had the lobster roll, and we both loved what we got. Came with Cape Cod chips, homemade pickles and they have a nice selection of take-out beers too.
East Norwalk is an underrated neighborhood right near the water. Two places to get ice cream, two takeout seafood spots, a fancier seafood spot, a pizza place/tavern, a pretty good deli and a good taco truck all in a 500 foot stretch of road.
