Shells Seafood is a chain in Florida, but the food is excellent and well priced. There is a location in St Pete and in North Redington Beach (between St Pete and Clearwater). Other favorites of ours are The Wharf in Pass-a-Grille (just south of the Don Cesar and the Friendly Fisherman in Johns Pass Village (Madeira Beach).
There's SO much good seafood in the area. . . .enjoy!!
