Any restaurants that will cook your catch? "hook & cook"

Generally the caveat is that you have cleaned the fish. Unfortunately I don't know of any restaurant in Seagrove that will do this currently.

I would see if Steamboat would be willing. The owner is usually there, and they are very down to Earth people.

Grayton Seafood Company is the closest one to Seagrove that I know of.

I know this is late and it's a little farther but Emeril's will do it 🙂
