Great seafood and fish stores can be found in any state, not just the coastal states. Fresh fish and seafood can be found in many different types of stores and locales. Sometimes there's a local fishmonger available. Good supermarkets carry a variety of fresh and frozen seafood and fish. If you live near the ocean, find out where the boats come in and go down there and see if there's a store or restaurant that will sell you the fresh catch of the day.
