Located on Hwy #1- the parking is very good.
Diann and I had been in search of upholstery adhesive to complete the solar panel wiring work that was done within the port berth closet of our Gemini catamaran sailboat. The fabric liner had to be pulled back to allow proper installation, and protection, of the new panel’s wiring. (This is the type thing that makes boat work continuous. What might seem like a short project has many “tentacles” to completion.)
While at an auto parts store, to purchase the can of spray adhesive, I spotted the restaurant called Fish Tales. It sells raw fresh sea food, and also has table seating for dining. If they sell fresh seafood, the meals have to be good. And they are.

I had the fried grouped plate. Diann had been craving a simple fried shrimp dinner. Slaw is a food about which I’m picky. The cold slaw was excellent- and I presume made on location vs. scooped from a tub. 
We were very pleased, especially since we seldom eat dinners for lunch!
Prices at Fish Tales range from $4.95 for a burger to $16.95 for one of their regular entrée’s. The regular menu is laminated. Their specials are put on a clip board.
