On the Crystal River waterway in Nature Coast Florida, Charlie’s Fish House is the essential local dining and drinking institution for the region — a straight-talking seafood restaurant and bar where the fish is as fresh as the river it came from and the atmosphere has the unhurried character of a small Florida river town. Scallops in season, fresh mullet, grouper, and the cold beers that make a riverside afternoon feel exactly right. The Crystal River area is best known for its manatee population and spring-fed waters, and Charlie’s has been feeding and watering the people who love this stretch of coast for decades.
